Ever notice how Protestant sects (like the CofC) that argue against the Immaculate Conception (Mary conceived free from original sin) believe all [other?] people are immaculately conceived?
Ever notice how “Bible-only” sects that believe Mary was a sinner can’t demonstrate from the “Bible only” one single sin she committed?
Ever notice how “Bible-only” sects believe Romans 3:23 (“all have sinned”) refers to Mary, but not aborted babies or Jesus?
The hunt to accuse Mary of sin is more satanic than Christian (cf. Revelation 12:10). All [Catholic] generations call Mary blessed, and full of grace, and the sinless mother of God. After all, Catholicism is the fullness of biblical Christianity.
