I think the word some of you may be grasping for is “prefigured.” Meaning that events seen in the Old Testament are fulfilled and completed or perfected in Christ’s coming and throughout the New Testament.
Noah’s Ark can be seen as prefiguring the one baptism that saves us. Just as Noah’s family was saved from God’s wrath in the ark, baptism cleanses us from our sins. Take a look at the readings from the Easter Vigil and you will see various allusions to how water was used by God to save from Noah to the Israelites fleeing Pharoah’s army.
The Ark of the Covenant was built to house the 10 Commandments or literally God’s own words. It doesn’t seem to me to be a stretch to see how Mary is a more perfect Ark by carrying Jesus, the word of God made flesh.
