No, the Immaculate Conception means that Mary was conceived without (original) sin.

The "Immaculate Conception" was made up out of whole cloth.

Wasn't "The Immaculate Conception" the conception of Jesus? To my knowledge only Jesus and Adam were created without the introduction of male and female sex cells (sperm and ovum).

I thought the "Immaculate" part of Jesus' Immaculate Conception was the fact that Mary "had not known man."

As far as Mary being "full of Grace," any forgiven sinner can tell describe the sensation of being "full of Grace."

[Not gonna take it anymore]

The Incarnation refers to the Holy Spirit overshadowing Mary.

The Immaculate Conception refers to Mary without original sin.

No, the Immaculate Conception was not the conception of Jesus, it was the conception of Mary. Catholic 101.

As far as Mary being "full of Grace," any forgiven sinner can tell describe the sensation of being "full of Grace."

In Catholic teaching, "grace" is not a feeling; it's a true, objective state of the soul, a participation in the Divine Life. The term often used is "sanctifying grace", which makes the soul pleasing to God. Adam and Eve lost this original gift by their sin, and it is restored to the Christian soul in Baptism. The restoration of grace was made possible by the sacrificial death of Christ on the cross.
