The letter detailed the ways in which the Equality Act discriminates against religious freedoms.
Four U.S. bishops, chairmen of U.S. Conference of Catholic Bishops committees or subcommittees, have signed on to a letter voicing religious freedom concerns with the Equality Act, introduced in the House this year.
They are part of a group of a dozen Christian leaders who signed the May 7 letter to House members.
In the letter, the signers said they have “grave concern over the devastating consequences to religious freedom” should the bill pass in its current form.
