From the website about the Hypostatic Order --All orthodox Catholic teaching.
The Order of the Hypostatic Union refers to those three person who belong to this ineffable mystery: the Incarnate Christ, Mary the Immaculate Conception, and Saint Joseph the Husband of Mary and Guardian of Christ. The Holy Family is the Order of the Hypostatic Union.
Saint Thomas Aquinas teaches that orders of ministries (either angelic or human) excel in proportion to their proximity to God (Summa theologiae I, q. 107, a. 6). Saint Joseph’s ministry and order, then, was higher than the ministry of the angels. Saint Joseph’s ministry, like that of Mary, is higher even than those of popes, bishops, and priests. This why traditional Catholic Church’s have altars to Mary and Joseph as testimonies to this truth. Mary and Joseph, with Christ, stand above all the orders and ministries of the supernatural order.
Francisco Suarez teaches that the ministry of Saint Joseph “surpasses all others because it exists in a superior order.” (Suarez, Tom II, disp. 8, sec. 1). Saint Francis de Sales holds to the same teaching. Moreover, all the theologians that compare the Holy Trinity to the order of the Holy Family confirm that the three persons of Holy Family belong to an order and ministry above all others.
And Yes, tradition DOES hold that St. Joseph was sanctified in the womb, and was born without Original Sin, and never sinned during his entire life and that his glorious holiness was only exceeded by his Virginal Spouse, Our Blessed Mother.
