A pernicious error that resurfaced in the preceding century is to say that babies who die without Baptism enter Heaven.  This effectively denies the existence of Original Sin.  Had the Church defended the necessity of Baptism, would Catholics have given in so easily to abortion and birth control?

The Church teaches infallibly that children must be baptized to enter Heaven.  The Council of Carthage under Pope St. Zosimus (A.D. 418), in defending infant baptism, declares:

Likewise, if anyone says that it might be understood that, in the kingdom of Heaven, there will be some middle place or some place anywhere that infants live who departed this life without Baptism, without which they cannot enter the kingdom of Heaven which is eternal life: let him be anathema.

For when the Lord says: `Unless one be born again of water and the Holy Ghost, he shall not enter into the kingdom of God' (St. John 3:5), what Catholic will doubt that he will be a partner of the devil who has not deserved to be a co-heir of Christ?
