WASHINGTON — Responding to a challenge from 55 of the 73 Roman Catholic Democrats in the House of Representatives, key leaders of the American church said that "all Catholics are obliged to shape our consciences in accord with the moral teaching of the church." That includes teaching on abortion, the prelates said.

The statement came from the chairmen of three panels of the U.S. bishops' conference: Cardinal Theodore McCarrick, of a special task force on Catholic politicians; Cardinal William Keeler of the pro-life committee and Bishop Nicholas DiMarzio of the domestic policy committee.

In a Feb. 28 joint statement, the 55 House members had addressed abortion and other matters, saying "we seek the church's guidance and assistance but believe also in the primacy of conscience."

The House members said they agree with Catholic social principles on poverty, education, health care and war and "the undesirability of abortion," but there is "disagreement with the church in some areas."

The three church leaders responded: "It is essential to remember that conscience must be consistent with fundamental moral principles."
