I think the dichotomy of Catholic vs. Protestant in this instance is a false one. Even among Protestants, there will be great differences regarding acceptance of this behavior (abortion, premarital sex, homosexuality, stem cell research, children outside marriage, gambling, divorce) between denominations. Probably greater thhan what this poll described.
For example, Episcopalians, ELCA Lutherans, UCC, etc, are quite probably more likely to sanction this behavior than are Traditional Anglicans, LCMS Lutherans, some Baptist Groups, and non-denominational “born again” Christians are.
Another problem I see, regarding the rearing of children, is far too many Christians leave the responsibility of teaching spiritual matters and values of the their children to the “church” rather than themselves. Considering the liberal infiltration of so many seminaries, it would not be surprising that the younger generation has adopted a more lax attitude toward morality.
This is neither a Catholic nor Protestant thing, but one where one follows Jesus Christ or you don’t. True believing Catholics and Protestants need to crack the Good Book open and teach from it. What we are seeing in Christendom today is carnal lukewarmedness and apostasy which is something that has plagued Christianity since the New Testament has been written. What Paul wrote in Phillippians 3:18-21 speaks perfectly to the moral mess we see today:
18For many live as enemies of the cross of Christ; I have often told you of them, and now I tell you even with tears. 19Their end is destruction; their god is the belly; and their glory is in their shame; their minds are set on earthly things. 20But our citizenship* is in heaven, and it is from there that we are expecting a Saviour, the Lord Jesus Christ. 21He will transform the body of our humiliation* so that it may be conformed to the body of his glory,* by the power that also enables him to make all things subject to himself.
I agree with what you have posted and have to add that many orthodox Catholics are now actively praying for the cleansing of the Church. I believe this has already begun and will continue. Remember that the gates of hell will NOT prevail....
