Daniel Avila is in hot water for a column that blames the devil for people being gay.

Avila, a policy adviser for the U.S. Conference of Catholic Bishops' (USCCB) Subcommittee for the Promotion and Defense of Marriage, unofficially refers to himself as “the bishops' marriage guy” and has represented the USCCB on the issue of gay marriage at conservative panels.

In the first part of an op-ed printed last week in the Boston Pilot, the official newspaper of the Archdiocese of Boston, Avila attempted to address the causes of same-sex attraction.

“The scientific evidence of how same-sex attraction most likely may be created provides a credible basis for a spiritual explanation that indicts the devil,” his column concludes.

On Wednesday, the paper retracted the piece and issued an apology, saying it “failed to recognize the theological error in the column before publication,” but did not provide any details of Avila's error.

In a statement, Avila also apologized, adding that “the Church opposes, as I do too, all unjust discrimination and the violence against persons that unjust discrimination inspires.”

DignityUSA, the nation's largest group of LGBT Catholics, called for Avila's dismissal.

“This shows that Catholic officials are willing to go to extremes in their anti-gay campaign,” said the group's executive director, Marianne Duddy-Burke. “[T]he Archdiocese of Boston and the USCCB should immediately terminate their relationship with Mr. Avila.”
