That is an absurd attempt which denies the obvious, since not only is the protestantism that is liberal a rebellion against the basic evangelical core truths of Protestantism (and which once was against contraceptives), esp. that of holding Scripture to be the wholly inspired literal word of God (though using different literary genres), while it is the majority of Catholicism that is overall far more liberal than her evangelical counterparts today.
And if you want to blame protestantism on that, then you indict them as following a multitude to do evil, rather than following those who better represent classic Protestantism in their basic truths and moral views, and even weekly RCs are less conservative.
In addition, Rome treats such as members in life and in death, even notorious public ones, thus manifesting what she really believes and teaches.
Contrary to the cherished image RCs have, this is the reality of your church which are bond to defend, and these liberals are your brethren, and you must own them.
A sub-rebellion of the original rebellion? I fail to see how that is any better. I might even be willing to concede that modern day Catholics (particularly in the western world) are more liberal than their evangelical counterparts.
Which means exactly what? Nothing. It’s the theological equivalent of, “my Dad can beat up your Dad.” We’re talking about Truth here. The Truth about the evil of birth control which has been taught by the Catholic Church since the beginning. And as Catholics, our sin is the greater one for disobeying for we have been given the fullness of Truth.
And what of the basic truths and moral views of protestantism? Sola scriptura? The abdication of the true Scriptures in favor of those adulterated versions that came later? Resulting in confusion within the Body of Christ. A horribly detestable state if there ever was one.
Sola fide? Resulting in the rejection of Christ’s sacraments and the sanctifying grace it imparts as expressed in scripture and preserved by the Church? Treating them with derision by denying the miracle of the Eucharist and calling it “magic”?
Coupled all this with the protestant-inspired radical individualism and what have you got? The current moral state of western civilization. This is the end result of that rebellion. Sure it’s generated some ancillary benefits (if you can call them that) such as the United States, the Constitution, etc. but as we see that today that doesn’t count for much.
What we are seeing today is the the end result of the protestant rebellion. And when it fades away along with its multitude of scriptural and theological error the only thing left standing will be the Roman Catholic Church. Which is why there really is no such thing as the betters of classical protestantism.
