I thought this beautifully written excerpt would be thought-provoking reading for Christians who wonder at Catholics who pray to Mary. This was written by Saint Louis-Marie Grignion de Montfort, who was a true Marian devotee and advocate of the same. It was the gospel commentary from dailygospel.org from today's Mass. The Gospel reading is from John 15:1-8.
[Jesus] is our only master, who must teach us; our only Lord, on whom we must depend; our only head, to whom alone we should belong; our only model, whom we should imitate; our only physician, who must heal us; our only shepherd, who must feed us; our only Way, who must lead us; our only Truth, whom we must believe; our only Life, who must be our life; and our sole sufficiency in all things, that in him we may have all in All. Except the Name of Jesus, there is no other name given under Heaven whereby we must be saved; and apart from Jesus Christ, God has given us no other foundation of our salvation, our perfection and our glory: "for other foundation no man can lay, but that which is laid; which is Christ Jesus" (1Cor 3:11). Every house which is not built upon this firm rock, is founded on the shifting sands, and will inevitably fall sooner or later. Every soul who is not united with Christ as a branch to the stem of the vine, will fall off, wither and become fit only for the fire. If we are in Jesus Christ and Jesus Christ in us, we need not fear damnation; neither angels in heaven nor men on earth, neither demons in hell nor any other creature can harm us because they cannot separate us from the love of God in Christ Jesus (cf. Rm 8:38-39).
