You don't get it. The question is not really "Should divorced and civilly remarried people receive communion?"

The question is really, "How do Catholics know what Christ wants them to do?"

The official answer has been for almost five hundred years that the faithful learn the will of Christ from the Magisterium of the Church. Specifically, something that has been taught by all bishops ever since the time if Christ is considered to be known to be part of the original teaching of Christ, transmitted by the apostles.

So the real question is whether the Pope thinks this principle should be done away with; and if so, whether it's really a good idea to do away with it; and if so, is this something the Pope can even decide.

Everybody has sympathy for the divorced and civilly remarried. But a lot of people think abandoning a fundamental epistemological principle should not be done by deliberate obfuscation and ambiguity.
