Yeah his argument about "social rebuke" is pretty ridiculous considering it is pretty obvious those who "gave up natural relations" are not exactly being complimented in Romans. Even if the words used translate to "unnatural" without ethical connotations, clearly these people are not "held in dishonor" in the same way Paul calls himself "held in dishonor". This is obviously not a passage where the people in question are being praised for going against society by following God.
not sure if he is Catholic or not, many denominations call their clergy "priests"...but the question of this thread is whether his argument regarding what the bible teaches about a certain subject is sound, not what denomination he belongs to.
He was ordained a Catholic priest at age 17, served the Church for 8 years as a priest in the Diocese of Pittsburgh and teaching in a seminary. Then, he became dissolusioned and left the Church because he no longer believed in its teachings. He left the priesthood, enrolled at the University of Texas, and is now a professor at the University of west Georgia. He is an advocate for DignityUSA, a pseudo-Catholic apostate organization devoted to petitioning the Vatican to change the Church's sexual teachings.
