Did Mary get baptized? Did she even need to?

[Mintaka]

The forgiveness of sins is important to Baptism, but the effect that lasts longest and leaves an eternal mark on the soul is that we die to ourselves and rise again as a body part of Christ’s Body.

So yes, Mary would have received many great graces at various times in her life, but definitely Mary would have been baptized (by Jesus or the Apostles under Jesus’ supervision). Otherwise, she wouldn’t have been a Christian of the New Covenant, but rather, she would have been assumed into Heaven solely as a member of the Old Covenant.

 

[OrbisNonSufficit]

My point was that she did those after her salvation was granted, not in order to be saved - so in Catholic thinking she was saved without any professed faith and without first doing any works?

Yes and no. God exists outside time. For example our Lord celebrated Eucharist at Last Supper before He Sacrificed himself. It’s also somewhat paradoxical.
