Many Christians no longer stand with Christ in the area of morality as laid out in Holy Scripture and the 10 Commandments, believing that mercy killing (Euthanasia), homosexual acts and unions, contraception and abortion are good for society and should be legal and hence are no longer Christian.
In an address given during that 1976 Eucharistic Congress in Philadelphia for the bicentennial celebration of the signing of the Declaration of Independence, Cardinal Karol Wojtyla spoke some words which I believe were prophetic. -
"We are now standing in the face of the greatest historical confrontation humanity has ever experienced. I do not think that the wide circle of the American Society, or the whole wide circle of the Christian Community realize this fully. We are now facing the final confrontation between the Church and the anti-church, between the gospel and the anti-gospel, between Christ and the Antichrist. The confrontation lies within the plans of Divine Providence. It is, therefore, in God's Plan, and it must be a trial which the Church must take up, and face courageously.
