RE: The ones in our ranks don’t even bother to argue that what they are doing is defensible according to Church teaching. They either publicly denounce Church teaching or they hide.
I refer you to the likes of Nancy Pelosi, John Kerry, Andrew Cuomo and many other Pro-gay, pro-abortion Roman Catholics who are shaping the future of this country. I don’t see them hiding.
In fact, they are setting PUBLIC POLICY.
You seem to have missed the point.
All three openly admit that they disagree with Church teaching.
Not one of them argues that their indefensible positions are based on Catholic tradition. Whenever they defend themselves against critics, they use secular or heretical arguments for their position because they cannot proceed on Catholic principles. They basically argue: "We are keeping up with the times: the Church is backward now, but we think it will catch up to us."
Vines, by contrast, builds his arguments on at least two core principles of the Reformation: the principle of the sufficiency of Scripture and the principle of private judgment of Scripture.
