The Catholic Church acknowledged its mistake in the handling of the inquisition of Galileo in October 1992 in Pope John Paul II's "Lessons of the Galileo Case." The Pope also issued an apology later on, within a larger apology acknowledging other mistakes of the inquisition, in March, 2000.
I'm very aware of this, the release some of the Inquistion's records has been fascinating to me. So a more precise claim would be that the Church doesn't "endorse" scientific theories as of 1992?
