No, it wouldn't.
Specifically, per the church rules the Priest cannot refuse them communion because of this opinion. And even if it had the power you give it those who chose to follow his opinion would do a penance and then receive communion.
a penance would first require that the person in a state of sin confess their sin and repent it with the understanding that they would not repeat the sin
anyone that supported a pro-choice person or decision would then re-offend
i suppose that anyone that repeated the sin could confess and perform penance again, but could they truly repent
i think that the catholic church's position is that anyone that performs or assists an abortion or has an abortion has committed a deadly sin
though they could confess, repent and perform penance - imo, it is too close to being political and not purely religious
i wonder what the irs thinks about it
should religious institutions that have a tax exempt position be allowed to foment political activity
of course religious institutions have opposed slavery and other wrongs by following their moral compasses, but once more, should they retain their tax exempt status if they choose to do so
another example would be the mormon church's (church of jesus christ of later day saints) opposition to homosexuality and homosexual marriage - a secular activity performed by a sectarian body
