A committee of U.S. Catholic bishops is getting to work on a policy document that has stirred controversy among their colleagues before a word of it has even been written.

The U.S. Conference of Catholic Bishops overwhelmingly approved the drafting of a document "on the meaning of the Eucharist in the life of the Church" that some bishops hope will be a rebuke for politicians who support abortion rights but continue to receive Communion.

The 168-55 vote to proceed, vehemently opposed by a minority of bishops amid impassioned debate during virtual meetings, came despite appeals from the Vatican for a more cautious and collegial approach.

Here's a look at what has happened and what lies ahead:

IS THIS AIMED AT PRESIDENT JOE BIDEN?

The chairman of the USCCB's doctrine committee, Bishop Kevin Rhoades, says no decisions have been made on the final contents of the proposed document but that it will not mention Biden or other individuals by name.
