These sublime truths, which so clearly show forth the infinite goodness of the Holy Ghost towards us, certainly demand that we should direct towards Him the highest homage of our love and devotion. Christians may do this most effectually if they will daily strive to know Him, to love Him, and to implore Him more earnestly; for which reason may this Our exhortation, flowing spontaneously from a paternal heart, reach their ears. Perchance there are still to be found among them, even nowadays, some who, if asked, as were those of old by St. Paul the Apostle, whether they have received the Holy Ghost, might answer in like manner: "We have not so much as heard whether there be a Holy Ghost" (Acts 19.2). At least there are certainly many who are very deficient in their knowledge of Him. They frequently use His name in their religious practices, but their faith is involved in much darkness. Wherefore all preachers and those having care of souls should remember that it is their duty to instruct their people more diligently and more fully about the Holy Ghost--avoiding, however, difficult and subtle controversies, and eschewing the dangerous folly of those who rashly endeavor to pry into divine mysteries. What should be chiefly dwelt upon and clearly explained is the multitude and greatness of the benefits which have been bestowed, and are constantly bestowed, upon us by this Divine Giver, so that errors and ignorance concerning matters of such moment may be entirely dispelled, as unworthy of "the children of light." We urge this, not only because it affects a mystery by which we are directly guided to eternal life, and which must therefore be firmly believed; but also because the more clearly and fully the good is known the more earnestly it is loved. Now we owe to the Holy Ghost, as we mentioned in the second place, love, because He is God: "Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole strength" (Deut. 6.5). He is also to be loved because He is the substantial, eternal, primal Love, and nothing is more lovable than love. And this all the more because He has overwhelmed us with the greatest benefits, which both testify to the benevolence of the Giver and claim the gratitude of the receiver. This love has a twofold and most conspicuous utility. In the first place, it will excite us to acquire daily a clearer knowledge about the Holy Ghost; for, as the Angelic Doctor says, "the lover is not content with the superficial knowledge of the beloved, but striveth to inquire intimately into all that appertains to the beloved, and thus to penetrate into the interior; as is said of the Holy Ghost, Who is the Love of God, that He searcheth even the profound things of God" (1 Cor. 2.19; _Summ. Theol_., 1a, 2ae, q. 28, a. 2). In the second place, it will obtain for us a still more abundant supply of heavenly gifts; for whilst a narrow heart contracteth the hand
