Jesus Christ our Savior, true God and true Man, ought to be the last end of all our devotions, else they are false and delusive. Jesus Christ is the Alpha and the Omega, the beginning and the end, of all things. We labor not, as the Apostle says, except to render every man perfect in Jesus Christ; because it is in Him alone that the whole plenitude of the Divinity dwells together with all the other plenitudes of graces, virtues, and perfections.
It is in Him alone that we have been blessed with all spiritual benediction; and He is our only Master, Who has to teach us; our only Lord on Whom we ought to depend; our only Head to Whom we must be united; our only Model to Whom we should conform ourselves; our only Physician Who can heal us; our only Shepherd Who can feed us; our only Way Who can lead us; our only Truth Whom we must believe; our only Life Who can animate us; and our only All in all things Who can satisfy us. There has been no other name given under heaven, except the name of Jesus, by which we can be saved. God has laid no other foundation of our salvation, our perfection, or our glory, than Jesus Christ. Every building which is not built on that firm rock is founded upon the moving sand, and sooner or later infallibly will fall.
By Jesus Christ, with Jesus Christ, in Jesus Christ, we can do all things; we can render all honor and glory to the Father in the unity of the Holy [Spirit]; we can become perfect ourselves, and be to our neighbor a good [fragrance] of eternal life.
If, then, we establish solid devotion to our Blessed Lady, it is only to establish more perfectly devotion to Jesus Christ, and to provide an easy and secure means for finding Jesus Christ. Devotion to Our Lady is necessary for us… as a means of finding Jesus perfectly, of loving Him tenderly, of serving Him faithfully.
