A Texas priest says Catholics are duty-bound to oppose the legalization of gay unions.

Father Michael Rodriguez, parish priest of El Paso's San Juan Bautista Catholic Church, opined in an editorial published in the El Paso Times that being gay is immoral.

“Remember: Every single Catholic, out of fidelity to charity and truth, has the absolute duty to oppose (1) the murder of unborn babies, and (2) any and all government attempts to legalize homosexual unions.”

“Any Catholic who supports homosexual acts is, by definition, committing a mortal sin, and placing himself/herself outside of communion with the Roman Catholic Church.”

Rodriguez does not mention what motivated him to write his fiery op-ed, but in May the El Paso Times reported that a lesbian couple had married in San Antonio after being turned down by El Paso authorities. One of the women, Sabrina J. Hill, is transgender. Under Texas law she is considered a man, making her eligible to marry her longtime girlfriend Therese “Tee” Bur. The story attracted international headlines.

While Rodriguez urges followers to treat gay people with “love, understanding and respect,” he quickly adds that “homosexual acts lead to the damnation of souls.”

“Abortion and homosexual acts are unequivocally intrinsic moral evils. And friends, this objective truth doesn't depend on the opinion of the majority. Frighteningly, if the majority chooses to deny the objective moral order, then we will all suffer the pestiferous consequences.”
