LGBTQ persons are serving in ordained ministry in various denominations currently and the predicted denominational collapses have not taken place.(1) The real harm is being done however by our continuing to fight over this issue, which damages the peace, unity and purity of the church particular and universal, as well as the witness of the church to the world.(2)
Furthermore, we must never shrink from doing what is right for the sake of protecting our denomination. Even if acting justly causes a mass exodus from our denomination, that is no reason to continue to act unjustly.(3)
1. This issue has been addressed in the UCC, ELCA, UU, Episcopal Church, MCC, the GAAAP, the RPI, Religious Society of Friends, the Swedenborgian Church of North America, the Uniting Church in Australia, and others, all of which ordain "practicing" LGBTQ persons. Other churches like the United Methodists and even the Moravian Church are where the PC(USA) is - actively moving toward LGBTQ ordination. As you can see from the long, robust, and growing list of churches ordaining LGBTQ persons, there has been no great collapse. Their ministry and witness is not compromised. In fact, these open and affirming denominations and organizations are in a better position than the PC(USA) currently is - they are benefiting from the calling, gifts and fruits of their sisters and brothers.
2. What is certainly tearing denominations apart is the lethal attempt to combine the Gospel with bigotry.
3. We cannot imagine one who loves and follows Jesus Christ choosing the life and health of the denomination over their life with God. The Protestant Reformation, which resulted in so many denominations today, was a catastrophe for the Roman Catholic Church, breaking apart its stronghold in Europe at the time. Should we then say that the Reformation should never have happened?
