I don’t think the position of the church is unclear at all.
I do know that some bishops in certain liberal theological/political enclaves will allow it to be obscurred....Notre Dame being an example.
Actually Bishop of Fort Wayne-South Bend, John D'Arcy was one of if not the first bishops to condemn the speech. To date, over five dozen other American bishops have stood in solidarity with him on this.
While you are correct that a disturbing number of bishops (typically from liberal enclaves) have for too long been silent on abortion, it should also be noted that NONE have ever spoken in favor of abortion.
