What is the Immaculate Conception?

In order to give birth to our Lord Mary needed to be totally pure…

A brief overview of the history and significance of the feast of the Immaculate Conception which is celebrated during Advent on Dec. 8th thoughout the whole Church.

Catechism 491. Through the centuries the Church has become ever more aware that Mary, "full of grace" through God, was redeemed from the moment of her conception. That is what the dogma of the Immaculate Conception confesses, as Pope Pius IX proclaimed in 1854:
“The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Savior of the human race, preserved immune from all stain of original sin.“

Original Sin and Infant Baptism

The Church´s teaching on infant baptism flows directly from the church´s teaching on original Sin and the sacrament of baptism itself. In other words, in order to make an argument for infant baptism, it is imperative that we understand and be able to explain the church's teaching on original sin, first and foremost and also to be able to understand and explain the churche's teaching on the sacrament of baptism itself.

Romans 5:12-21. Therefore as sin came into the world through one man and death through sin, and so death spread to all men because all men sinned sin indeed was in the world before the law was given, but sin is not counted where there is no law. Yet death reigned from Adam to Moses, even over those whose sins were not like the transgression of Adam, who was a type of the one who was to come. But the free gift is not like the trespass. For if many died through one man's trespass, much more have the grace of God and the free gift in the grace of that one man Jesus Christ abounded for many. And the free gift is not like the effect of that one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brings justification. If, because of one man's trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ. Then as one man's trespass led to condemnation for all men, so one man's act of righteousness leads to acquittal and life for all men. For as by one man's disobedience many were made sinners, so by one man's obedience many will be made righteous. Law came in, to increase the trespass; but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness to eternal life through Jesus Christ our Lord.
