Holy Trinity–St. John the Theologian Greek Orthodox Church in Jackson, Mississippi, is a welcoming parish of the Greek Orthodox Metropolis of Atlanta, rooted in the ancient faith and traditions of Orthodoxy. We have been serving the Jackson area for over 70 years, the last fourteen of which have been in our current location. The parish serves the Jackson community through worship, fellowship, education, and ministries that reflect the love of Christ and a commitment to spiritual growth.
