While, strictly speaking, this is a sermon and not a conference or catechism, Fr. Hewko's "The Grandeur of the Ceremonies of the New Testament!" is too important not to receive special attention. It is a powerful reminder of how the Priesthood and the Holy Sacrifice of the Mass were both foreshadowed in the Old Testament and how they were both brought to their perfection in the New Testament.
"So let us be confident, let us not be unprepared, let us not be outflanked, let us be wise, vigilant, fighting against those who are trying to tear the faith out of our souls and morality out of our hearts, so that we may remain Catholics, remain united to the Blessed Virgin Mary, remain united to the Roman Catholic Church, remain faithful children of the Church."- Archbp. Lefebvre 1980
