As intellectual gymnastics go, this one is the equivalent of touching one's tailbone with one's nose. The definitive beliefs- the boundaries, if you will- of a religion are not defined by majority vote any more than truth is. In Catholicism, the boundaries are established by the magisterium; in the other Western Christian traditions, they're established by the Bible.
To reject those boundaries- as the Irish people have- is to reject the tradition. And it's worth noting that only those few, marginally Christian communities have embraced homosexuality and same-sex "marriage" which minimize or reject the authorities which supposedly set the boundaries that define their religion. I have no doubt that in many cases the stand in favor of same-sex "marriage" taken by Irish voters was based on their faith. The problem is that their faith is no longer Catholic in any meaningful sense- or even Christian.
A Catholic- or a Christian- is by definition one who accepts the teachings of Catholicism or Christianity. And the teachings of both- regardless of what a majority of those claiming identity with Catholicism or Christianity may say- unambiguously reject homosexual behavior and define marriage as being, by divine mandate, between one man and one woman.
And how's this as a nominee for the most nonsensical comment of the year: "A community which excludes anybody is no community at all."
Actually, a community which doesn't exclude a great many people is no community at all. It's the human race. it has no other boundaries than that, is totally without any particular significance, and, as a community, utterly without definition or substance.
Which is kind of the problem with cafeteria Christianity and the kind of nonsensical, brain-dead postmodern bilge the article in question is trying to sell. Words mean things, communities stand for things- and if they don't, they're nonsensical vocalizations and meaningless abstractions, not words or communities.
No doubt the Irish people did express their faith precisely through their vote. The trouble is that their faith is neither Catholic nor Christian. A faith which authorize one to discard any part of divine revelation one doesn't like is ultimately the idolatry of self, and nothing else.
