Here is another wonderful (and at the same time, very scholarly and thought provoking) sermon by Fr. Cantalamessa, the Pontifical Household preacher.
It is not just a moving sermon but one I'd call a spiritual chiropractor spine realignment, teaching those who read and revere St. Paul how to actually understand his full relationship with God and Jesus Christ. This has been a stumbling block for many Reformation children.
