Before his conversion, Dr. Acosta had studied to become a Roman Catholic priest. A change of mind, though, prompted him to pursue a different career, and he acquired degrees in Education and School Administration at Temple University in Philadelphia, Pennsylvania.
As he held the position of School Administrator in Philadelphia, Dr. Acosta became interested in reading the entire Bible for the first time, searching for the doctrine of Purgatory, which is a common belief in the Roman Catholic Church. He found no evidence for Purgatory in the Bible; instead, he found the doctrine of Salvation by faith alone, through Christ alone and by the grace of God alone.
His newfound love for the Scriptures and God motivated him to go back to the seminary, this time an Evangelical Reformed one, where he completed his M.Div. and Doctorate degrees. The title of his dissertation is A Comparative Study of the Bible with the Official Doctrine of Roman Catholicism. The Roman Catholic Church responded to his dissertation with a book and invitations to public debates.
Dr. Acosta was invited for a theological debate in Bogota, Colombia. After the debate, the majority of the audience believed the Bible. In response to this high interest, Dr. Acosta and his wife, Mimi, founded Gospel Through Colombia, under the authority of Calvary Presbyterian Church and Dr. James Montgomery Boice, who was pastor of Tenth Presbyterian Church of Philadelphia.
GTC ministry, now SRL Seminary, has been blessed and used by God to bring the XXI Century Reformation to Latin America, by providing theological education to thousands of pastors and ministers of the gospel. Seminario Reformado Latinoamericano is located on 14 campus sites in several countries, and provides online education, as well.
For the past nine years, Dr. Acosta has been engaged in teaching ministry of Bible studies at St. Andrew’s Chapel, in Sanford, Florida.
