Everything depends on how you define everything, doesn't it? However, my original statement stands unassailed, unless by "changing doctrine" one means not changing doctrine but something else, perhaps "having an influence on implementation," or ... what you will, since the question is, "Who's to be master, words or us?"
How about “burying doctrine” or “making doctrine optional” or “Not changing doctrine in theory, Oh No! Merely in practice”?
But Cardinal Kasper (whose book the Pope praised) claims that allowing divorced and remarried not living as brother and sister to take communion would not affect doctrine, but that is clearly not the case. It contradicts Our Lord’s teaching that this situation is adultery, and St. Paul’s teaching that one should not take communion unworthily (i.e., in unrepentent mortal sin). So the proposal, seemingly being pushed by the Pope DOES affect doctrine quite directly and would be a disaster for the Church, opening the way for anyone to completely ignore the Church’s moral teachings and take communion with the Church’s blessing.
