Context is all, here. Christ's pronouncement while on the Cross shows what He wanted to be known about Mary.
Let's see. When were the Deuterocanonicals canonized? In the late 300s, I believe. Did they need to be canonized then to promote some heinous plot?
Neither the Pope or any Ecumenical Councils “officially” approved of the canons until the Council of Trent. Look it up. Given the historical errors included in the Apocrypha I cant see how they view them as inspired by the Holy Spirit.
