A Church Built from the Pulpit Out
On a residential block of Edmund Street in Aberdeen, the seat of Harford County, sits Aberdeen Bible Church, a Bible-believing congregation whose present building was raised by its pastor and members during his second year there. That pastor, Dr. Nathaniel Johnson, has now led the church for 35 years. In that time the congregation has grown into a hub of ministries, choirs, conferences, and a community nonprofit that extends well past the front door of 529 Edmund Street.
Worship on Sunday and Wednesday
Sunday School begins at 9:45 a.m., followed by the morning worship service at 11:00 a.m. The weekly rhythm continues on Wednesday evenings with prayer at 7:00 p.m., discipleship teaching at 8:00 p.m., and youth classes running at the same hour. Services are carried online through the church's Facebook page, where a "Watch Us Live" stream links visitors to the broadcast.
The worship blends adult and men's praise teams, the church choir, and the ABC Dance Ministry, which ministers through movement and praise dance under the direction of Candace Johnson. Hymn favorites among the leaders include "Am I a Soldier of the Cross," "I Must Tell Jesus," and "Revive Us Again," giving the music a traditional feel rooted in Scripture. Pastor Johnson preaches expositionally, working through books of the Bible verse by verse with a teaching he describes as Bible-centered, life-applied, and grounded in the inerrancy of the Word.
Thirty-Five Years of Pastor Johnson
Dr. Nathaniel Johnson grew up in the Philadelphia area and answered the call to ministry in 1984 under the late Timothy E. Ruffin of Beulah Baptist Church. He trained at Temple University, where he earned a Bachelor of Science in accounting and business law, then completed a Master of Divinity at Philadelphia Episcopal Seminary and a Doctor of Ministry at Faith Theological Seminary in Baltimore. Licensed and ordained by Pastor Ruffin and Pastor James Johnson of Shining Star Baptist Church, he came to Aberdeen Bible Church and has now served the congregation for 35 years.
His life verse, 2 Timothy 2:2-3, anchors a ministry of discipleship that prizes expository preaching and the inerrancy of Scripture. He and his wife, First Lady Roslyn Johnson, who joined him in the work at ABC in 1987, have raised five daughters, all graduates of Villanova, Widener, Albright, West Chester, Morgan State, and Towson universities. The family now includes a son-in-law, MacKenzie Middaugh, and grandsons Kraven and Lucian. Pastor Johnson founded the first men's fellowship in Harford County and currently leads a building campaign to add an outreach center and school to the church property.
The First Lady and the Women's Work
Roslyn Johnson, the First Lady of Aberdeen Bible Church, has long overseen the women's ministry and teaches in the children's Sunday and midweek Bible studies. She came to know Christ as a teenager at Mount Pleasant Baptist Church in Baltimore, the Carters' family church, where she sang in the choir, ushered, and attended services week after week. After marrying Nathaniel in 1977, the couple moved to Philadelphia in 1976 and joined Beulah Baptist Church under Pastor Ruffin, whose teaching shaped her Christian walk. Back in Maryland they joined Shining Star Baptist Church, and together they planted a community outreach ministry called Fellowship Ministry that grew, under pastoral leadership, into what is now Inner County Outreach.
When the Lord moved the Johnsons to Aberdeen Bible Church, Roslyn continued to teach and lead the women's ministry and the children's Sunday and Wednesday Bible study. The women's ministry she leads today follows an acrostic called "Adorned" - Arrayed, Disciplined, Obedient, Righteous, Newness, Encouraging, Disciples - and gathers women around weekly Bible studies, monthly fellowship events, an annual conference, and community service projects.
Eleven Articles of Faith
The church's doctrinal statement sets out eleven beliefs that shape its teaching and life. Members affirm the verbal and plenary inspiration of the original manuscripts of the Old and New Testaments as the inerrant Word of God and a trustworthy rule of faith and practice. They confess the Trinity of Father, Son, and Holy Spirit, coeternal, coexistent, coequal, omniscient, and omnipresent while remaining in essence one God. They affirm the deity, virgin birth, sinless life, substitutionary death, bodily resurrection, and imminent return of Christ. They believe in the personality of the Holy Spirit, by whom believers are called, regenerated, baptized, indwelt, sealed, and filled for Christian service. They hold to the direct creation of the universe and man by God apart from any process of evolution. They confess the fall and total depravity of the race and salvation by grace through faith in Christ, whose blood was shed for the remission of sin. They believe in the unity of all true believers as the universal Body of Christ. They view the local church as a self-governing body of regenerated, baptized believers with pastors, elders, and deacons as officers. They affirm the personal existence of angels, demons, and Satan. They look for the imminent return of the Lord Jesus to receive His own people into the joys of Heaven and the ultimate eternal damnation of those who reject Christ in the lake of fire. They believe in the everlasting and eternal blessedness, bliss, and joy of all those who are in Jesus Christ their Lord.
Inner County Outreach
From the church's ministry grew Inner County Outreach (ICO), a faith-based nonprofit that Pastor Johnson founded and now leads. ICO employs 23 full-time, 20 part-time, and seasonal staff, runs 13 human-service programs on an annual budget of $1.8 million, and partners closely with ABC to share the gospel in word and deed. Its focus is the whole person - spiritual, emotional, and physical - with a particular call to single female-parent households. ICO supports those households with mentoring, educational programs, financial services, mental health care, and basic family needs. Through ICO Community Day the nonprofit hosts health screenings, food distribution, family games, and workshops in and around Aberdeen, and ABC members volunteer alongside ICO staff on a regular basis.
Men's Ministry and Liberty House
The ABC Men's Ministry describes itself as informal and informational, with weekly Bible studies, youth and men's mentoring, community evangelism, prison ministry, and an annual conference. Its eight stated goals include reaching men with the gospel, building Christian role models, and supporting the broader vision of the church. Out of this ministry grew Liberty House, a substance-abuse recovery ministry that Guy Warfield has facilitated for over twenty years. Members also lead the Harford Detention Center ministry week after week, teaching and mentoring incarcerated men through Bible-based lessons. The men's fellowship welcomes men of all ages and backgrounds, regardless of how much church experience they bring.
Children, Youth, and the Trinise Jones Day Camp
Sunday School meets every Sunday morning at 9:45 a.m. with classes for children, youth, and adults. Karin Waters, who has directed the Youth Ministry for over twenty years and now serves in the Education Department, oversees much of the discipleship of the church's young people. Carlease Gwynn, who has worked in the children's and drama ministries at ABC since she was a child herself, continues to teach and lead alongside the next generation. Candace Johnson teaches the high school Sunday School class.
Each summer the church runs Vacation Bible School, a week-long program of Bible lessons, crafts, and games. The 2026 VBS walks children, teens, and adults through the Shepherd-King imagery of Psalm 23 from July 20 to 24, meeting each evening from 6:15 to 9:00 p.m., with tracks for kids, teens, and adults. The Trinise Jones Summer Day Camp extends that care through the warmer months with sports, arts and crafts, team-building, and character formation, giving children a place to learn life skills and deepen their understanding of God's love while forming friendships that last beyond the summer.
Annual Gatherings: Women's and Mission Conferences
Two flagship conferences anchor the church year. The Women's Conference gathers women of faith each spring for a weekend of worship, breakout sessions, and prayer centered on a scriptural theme. The 2026 gathering, "The Blessing," draws on Numbers 6:24-26 and includes a meet-and-greet on Friday evening, a Saturday morning arrival and breakfast, opening and closing sessions led by featured speakers, eleven breakout sessions running in two waves, a praise-dance presentation by the ABC Dance Ministry, lunch with vendors, and a raffle. Vendors can sign up to share their products and services with the women of the conference.
The Mission Conference, held in late September, focuses each year on a different facet of God's global work. The 2026 conference, "The Heartbeat of God," moves from Genesis to Revelation, exploring the great commission, the empowerment of the Holy Spirit, cross-cultural ministry, and the harvest fields waiting in everyday places. Saturday's schedule covers topics from "God's Heart for All Nations" to "Barriers Broken: The Cross-Cultural Heart of God," and Sunday extends the teaching through the regular morning schedule at ABC.
Discipleship, Discovery, and Membership
Those exploring membership at ABC walk through the Discovery class, a Wednesday-evening study required for new members. The Discipleship Ministry also oversees small groups and mentorship, pairing newer believers with seasoned women and men for accountability and growth. Bible studies meet on Wednesdays under pastoral leadership, with separate tracks for women, men, and youth. The Education Ministry coordinates Sunday School, adult Bible studies, and youth programs, equipping believers of every age to study the Bible and live out a faith-centered life.
Annual Rhythms of the Church Year
Beyond the weekly schedule, the church observes an annual calendar that includes a Black History Program, special Christmas, Easter, and New Year's services, Vacation Bible School in July, the Trinise Jones Summer Day Camp, ICO Community Day with health screenings and food distribution, ABC Praise in the Park - an outdoor picnic worship service - and Pastoral/Church Anniversary Week, a celebration of the pastorate and the congregation's growth together.
Leadership and Giving
Minister Tracy Kelly serves as Assistant Pastor alongside a team of deacons, ministry leaders, and directors for Women's, Men's, Education, and Discipleship ministries. Marjorie Warfield chairs the Female Deacon ministry. Bobbye Mathews and Alexander (Bernie) Brown serve as co-deacons, with Brown also heading the Usher Ministry and teaching Sunday School. Edna Johnson administers the Missions Ministry and coordinates the VITA Tax program at ICO. A transportation page fields questions about rides to services and special events.
Tithes and offerings, along with conference and event fees, are processed through Givelify, with conference tickets available through the church's online store. Members and friends from across Harford County gather at 529 Edmund Street each Sunday and Wednesday to worship, study, and serve - a community rooted in Scripture and reaching outward to Aberdeen and beyond.
