Civility is called for and this article contains it in spades. Bravo Cardinal.
But clarity is also called for and it is an ignoring of reality to not face the fact that the LCWR has embraced some Loony Tune ideas in direct conflict with the gospel. Errors need to be corrected as gently and charitably as possible, but smiling and tolerating the teaching of dangerous untruths under the banner of catholicism is neither charity nor civility. Sin DOES separate us from God. We DO all need a Savior. Our feelings are a poor substitute for revealed truth as a moral compass. Regardless of their personal sincerity and good intentions, anybody who teaches otherwise and claims the authority of the Church in doing so needs to be corrected. That what the bishops are for.
