Elders (also known as pastors) are those men whom the congregation chooses to watch over them spiritually, to lead them in the public worship of God, to feed them the Word of God both publicly and privately, to administer the ordinances of baptism and the Lord’s Supper, and to guard the church from doctrinal or practical dangers.  These elders are to be chosen in accordance with the requirements for such an office which are set forth in Scripture (e.g., 1 Timothy 3Titus 11 Peter 5, etc.).  A plurality of elders is not only the Biblical pattern, but also a true blessing from the Lord.  These elders may differ from one another in experience and gifts, and one or two may labor more often in the preaching ministry than the others, but they are all equal in authority and title.  The Apostle Paul teaches in Ephesians 4 that pastors and teachers are gifts from the exalted Christ to His church and are therefore to be highly esteemed for their work’s sake.

Campbell was born and raised in South Africa into a Christian home, attending the Empangeni Baptist Church. Campbell came to faith in Christ at age 13 at a youth outreach meeting. After high school, he completed a 3-year diploma in Theology at the Bible Institute of South Africa in Cape Town. During his time in seminary, Campbell encountered the Doctrines of Grace and embraced the Reformed Faith. Campbell was called back to labor at his home church for 6 months before being conscripted to the South Africa Defense Force for 2 years. Campbell later worked in engineering sales in South Africa in various cities, including Durban, where Campbell pastored a small Baptist church bi-vocationally before he was relocated for work after 1 year. In 1985, Campbell married his high school sweetheart, Robyn, from his home church. The family moved to the USA in 2002 as a result of a sales job offer in New Jersey. They became members of the Reformed Baptist Church of Lafayette, NJ, where Campbell served as an elder for 3 years. They moved to Redondo Beach, CA in 2009 when Campbell joined the fish business. They became members of TRBC soon after arriving in CA. Campbell and Robyn have 2 adult daughters, Gillian and Sarah-Jane and 3 grand-daughters. In his time off, Campbell enjoys being with his family, trying out new fish recipes and watching a good war movie.

Pastor Sean Garrett

In 2008 they were blessed with a son, Owen. Sam graduated from the University of California, Irvine with a Bachelor’s degree in Spanish Literature and Culture.

In September of 2012, he was ordained and installed at Trinity Reformed Baptist Church. Sam completed a Ph.D. at the Free University of Amsterdam in October 2017.
