Mark Achtemeier

Mark Achtemeier is a Presbyterian Church (U.S.A.) pastor and theologian known for his book 'The Bible's Yes to Same-Sex Marriage: An Evangelical's Change of Heart,' detailing his shift from opposing to supporting same-sex marriage and ordination of LGBTQ+ individuals in the church. Initially, in 1996, he wrote in favor of policies restricting ordination of openly gay and lesbian ministers, but personal experiences led him to advocate for change, contributing to denominational policy shifts in 2011. He has served as a leader in theological task forces and spoken at churches like Lewinsville Presbyterian.
