Because all Bergoglio is is a politician.
He wants adulterers to be given Communion. And abortionists, also. He has the support of Wuerl, Dolan, Chaput (regarding the pro-aborts, but not the adulterers), Cupich, Gomez, etc.
The original plan was to put out Amoris—a huge load of inconsistent, unreadable crap—while making clear what he wanted the end result to be, on the ground.
He didn’t figure on anyone’s actually reading his bafflegab. But the Four Cardinal’s did, and they identified four heretical implications in AL. And they asked for Yes or No in response.
The result has been weeks of tantrums, smears, innuendo, insults, demotions, slanders. But no answers.
The answers, btw, are: no, yes, yes, yes, yes.
The request for simple yes/no answers was a brilliant move by the four cardinals to "smoke" them out!
I think the ultimate sin is abortion. Once a sperm and egg unite, you have a human being. Hence, it may deny the opportunity of salvation for a human soul, which is the main purpose of existence.
