OF THE PERFECTION OF DIVINE LOVE WHICH EXISTS IN THOSE WHO HAVE ATTAINED TO BEATITUDE
THE only mode of loving God perfectly which is possible to rational creatures, is the mode which belongs to him that loves. In this manner a rational creature loves God with all the completeness of his nature. This is made clear in the precept of Divine love. We read in Deuteronomy (vi. 5), "Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul and with all thy strength." St. Luke (x. 27) adds, "and with all thy mind"; as if the "heart" regulated the intention, the "mind" the thought, the "soul" the affections, and the "strength" the activities. For all these must be devoted to the love of God. We must remember that this precept may be fulfilled in a two-fold manner. When anything is perfect, nothing is wanting to it. Hence, when the love of God is complete and perfect, He is loved with the whole heart, and soul, and strength; so that there is nothing within us which is not actually turned to God.
This perfect mode of love is not possible to those who are on the way to Heaven, but only to those who have reached their goal. Hence, St. Paul writing to the Philippians says (chap. iii. 12), "Not as though I had already attained, or were already perfect; but I follow after, if I may by any means apprehend." He writes as if he were hoping for perfection when he should have reached his goal, and when he should have received the palm of the blessed. But St. Paul does not use the word "attaining" in the sense of entire possession or perfect comprehension, for God in this sense is incomprehensible to every creature. By "attaining" he means reaching the end which he has been following and seeking. In Heaven, the understanding and the will of every rational creature is turned to God; since it is in the fruition of the Godhead that the beatitude of Heaven consists. For beatitude exists not in habit, but in act. And, since the rational creature will in Heaven cleave to God, the Supreme Truth, as to its last End, all its activities will, by intention, likewise be directed to that Last End, and will all be disposed towards the attainment of that End. Consequently, in that perfection of happiness, the rational creature will love God with its whole heart; since its whole intention in all its thoughts, deeds, and affections, will be wholly directed to Him. It will love God with its whole mind, for its mind will be ever actually fixed on Him, beholding Him, and seeing all things in Him, and judging of all things according to His truth. It will love God with its whole soul, for all its affection will be uninterruptedly fixed on Him, and for His sake it will love all things. It will love God with all its strength, since His love will be the motive governing all its exterior acts. This, then, is the second mode of perfect love, and this love is the portion only of the blessed.
