If only catholics who agree 100% with Church teachings took Communion, no one could honestly participate. I do not agree 100% with the Catholic Church, nor do I agree 100% with any other Church.
I also have received Communion in other Churches, been given several nice awards from the Methodist Church and one recognition from a Synagog. So far I haven't been denied Communion back in my home parish. I know the former Pastor of my Church encouraged people of other denominations to receove Communion with us. I know he would be speaking out against the ban.
I see a time when there will be an American Catholic Church, similar to the Episcopal Church.
All in all, it shows the wide spectrum of beliefs within the Catholic Community. I am certain Bush would be denied Communion at several Churches down this way.
This may actually help Kerry. There is a reason that a Catholic has not been elected since Kennedy.
