Indeed, Mary could have parted the Red Sea, but such speculation has no place as a doctrine, especially in the light of the fact that the Holy Spirit characteristically mentions exceptions to the norm among notable persons, from great age (Methuselah), to excess size, fingers (Goliath), strength (Samson), devotion (Anna), diet (John the Baptist), to the supernatural transport of Phillip, the singleness of Paul and Barnabas, and uncharacteristic duplicity of Peter, and the surpassing labor and suffering of Paul, etc., etc. to John the Baptist "being" Elijah, and Christ being sinless and the prophesied Messiah and Divine.
But Mary is nowhere presented as being a sinless perpetual virgin and highest created being in virtue, titled the mother of God and bodily assumed into Heaven and crowned as its Queen, with authority over angels, and hearing virtually infinite amounts of prayer from earth addressed to her, etc. .
Meanwhile, it is abundantly evidenced that Scripture was the transcendent supreme standard for obedience and testing and establishing truth claims as the wholly Divinely inspired and assured, Word of God.
And which testifies (Lk. 24:27,44, etc.) to writings of God being recognized and established as being so (essentially due to their unique and enduring heavenly qualities and attestation), and thus they materially provide for a canon of Scripture (as well as for reason, the church, etc.)
But the weight of Scriptural substantiation is not the basis for the veracity of RC doctrine, lest they be as evangelicals, but assurance of Truth for an RC is based upon the premise of the assured veracity of Rome.
Under which Scripture, history and tradition only assuredly consist of and mean what she says they do. For Rome has presumed to infallibly declare she is and will be perpetually infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
Well said!
