God “does not and cannot bless sin: He blesses sinful man, so that he may recognize that he is part of his plan of love and allow himself to be changed by him,” it said.
The left went insane within seconds, of course.
But -- the Church is not bound by the left, nor does it care. That's a feature, not a bug incidentally.
I have my quarrels with the Church but what you cannot argue with is that religions have the absolute right to choose who enters into their sacraments and on what terms. It doesn't matter if you agree with them or not. By definition faith cannot be proved, and what you can prove is not faith.
If you believe in the Catholic doctrine on marriage then there is no way to wordsmith your way into a "Catholic gay wedding." It can't be done; to do so is to deny that which the Catholic Church believes.
You can bless and respect a person, but not an act that is held to be a sin.
Under Catholic doctrine we are all sinners, intentionally so. We all do things that we know are in fact sins. Whether through inattention or malice doesn't really change much, since in point of fact as adults we're all responsible for paying attention, and if thus the willful refusal or failure to do so is equally chargeable as to intent.
Disagree with the Church if you'd like, but religion is not logical. By definition it requires that one take on faith what one cannot prove. Science has no answer in these matters, and never will.
Yet in many cases the most-logical of all are also religious.
Because for each answer we find there is another question, and we always run out of answers. Believe in the "Big Bang" all you'd like, but tell me -- where did all that matter come from? If you believe it's a cycle, what started it? If you believe it's a one-off and the universe is inexorably headed toward heat death how did it happen in the first place?
At some point you wind up with "I don't know."
No, you can't cancel Catholicism because it doesn't hew to your particular desires. Oh, you can try, but you will fail.
As you should.
