I read from a Christian forum that the Marian doctrines was grievous error.
Part of the problem in general is that many non-Catholic Christians do not read the Bible typologically. For example, Paul recognizes Biblical types between Jesus-Adam (
Rom. 5:14) or between the Old and New Covenants and Sarah and Hagar (
Gal. 4:21-31), etc… Catholics have recognized throughout history in the deposit of faith a number of Marian biblical types in the Old Testament. For example, the Ark of the Covenant bears unmistakable parallels to Mary (see
chart here).
If we compare Eve to Mary we see more parallels. In Genesis Eve is described as a “Woman” who disobeyed God. Genesis describes one woman (Eve) and one man (Adam) who are created initially immaculate. The woman and man are approached by one angel (who is fallen, the Devil) and they choose freely to disobey God and eat one food from one tree that would cause death for a whole race. In Luke’s gospel the same is seen but only in reversed and redemptive way. In Luke one woman (Mary) is visited by one angel (who is holy, Gabriel) and this one woman freely chooses to obey and accept God’s plan for her, unlike Eve. This one women would give birth to one man Jesus Christ who would die for all on a tree and give the world one food to eat that would give life to the whole human race (Holy Communion Jn 6:54-58).
And remember, in Biblical typology, the later type is always superior to the former, i.e. Jesus is superior to Adam, etc…
When we see Mary as the new Eve, we see the Immaculate Conception, because Eve was formed without original sin. When we see the Ark in heaven in the book of Revelation, this fortifies the idea of the Assumption, that Mary is already in heaven. When we see Mary as the Ark, we recognize Mary as pure (clad in gold) and not to be touched (perpetual virgin), etc… There are other figures about Mary such as Mary as the Church that also reveal Catholic doctrines on Mary.
Once one recognizes the strength of typology between the Old and New Testament, a whole world of truth pours out from the texts and traditions. That is why Catholics often “see” things in Scripture that non-Catholics do not. It’s not that Catholics impose or violate the text. On the contrary, it is Catholics following the “pattern of sound teaching” that Paul set forth. It is Catholics delving into the parallels and context of the texts.
