Matt, Ken, and Kenny continue their series on the Marian dogmas, discussing what they used to believe about Mary as Protestants, and how they came to embrace the Catholic teaching about her.

In their last two episodes, they began to discuss the Immaculate Conception of Mary, looking at the biblical themes of Mary as the New Eve and Ark of the New Covenant.

This week, they address the question: If this teaching is true, why did the Catholic Church wait until 1854 to define it as true?
