Peter Oddleifson was an elder at Third Presbyterian Church (Rochester, NY), an attorney who contributed to the national LGBTQ movement for equal ordination rights in the PC(USA), and an early member of That All May Freely Serve (TAMFS). TAMFS began in 1993 after Rev. Jane Adams Spahr, a lesbian minister, was banned by the Permanent Judicial Commission from accepting a call to serve as a pastor of Downtown United Presbyterian Church (Rochester, NY). Downtown Church formed TAMFS ministry in response, electing Spahr to serve as a "lesbian evangelist" to the PC(USA), and advocating for the full inclusion of LGBTQIA+ Presbyterians.
