The Commandment of Love of God

The Commandment of Love of God.—In the commandment of love of God two things are expressed: (a) the matter of the commandment is God, the object of love; (b) the manner of the commandment is that God be loved as the Last End, to whose love all other love is to be subordinated.

There is a twofold manner or mode of performing a virtuous act:

(a) The intrinsic mode is that which comes from the nature of the virtue commanded. Thus, in the Fourth Commandment is included not only the substance of an act (viz., that honor be shown), but also the mode of the act (i.e., that such honor and so much honor be shown as is owed to a parent by his child). The intrinsic mode is always included in a commandment along with the substance of the act prescribed (cfr. 480 sqq.).

(b) The extrinsic mode is that which belongs to some virtue different from the one commanded. This mode is not included in a commandment. Thus, if honor be shown to parents out of love of God, the mode of love of God is extrinsic to the commandment, for the commandment is concerned with the virtue of filial piety, and the mode of the act pertains to charity, which is a virtue distinct from filial piety.

The intrinsic mode of performing an act of virtue is also twofold:

(a) The essential mode is that without which an act is not virtuous. Thus, he who gives to his indigent parents according to his means and their needs fulfills the essential mode of the Fourth Commandment, for, if he gave them less than he could afford and they needed, his act would not come up to the requirements of the commandment.

(b) The ideal mode of the performance of virtue is that which adds to the virtue greater goodness and value, and which is intended by a lawgiver as the end, but not as the object of his command. Thus, he who gives to his indigent parents not only sufficiently, but also with a great willingness and cheerfulness, fulfills the Fourth Commandment with greater perfection than another who supports his parents with less alacrity.

The mode of the love of God prescribed in the first and great commandment is that God be loved with the whole heart, etc. But “to love with the whole heart, etc.,” can be understood in various senses.

(a) Thus, it may be understood to mean a love that is subjectively or intensively great, as when one loves God with much fervor and affection. This mode of love is ideal, since the measure of loving God is to love Him without measure, but it is not essential. The end of the commandment is that we love God ever more and more, and perform what is required with ever greater promptitude and gladness; but the commandment does not fix any certain degree of intensity, although it would be inordinate to choose to love God less intensely than we love creatures (see 1160).

(b) “To love with the whole heart” may be understood to mean a love that is objectively or appreciatively great, as when one esteems and loves God as the Supreme Good. This mode of love is essential, and hence without it the commandment is not observed. However much one loves God, if one does not love Him as the Supreme Good, one does not love Him aright, and does not practise the virtue of charity that is commanded.

Love of God from the whole heart, objectively or appreciatively understood, is either actual or habitual.

(a) Actually, one loves God with one’s whole heart when there is never any interruption or distraction to one’s love, and one is continually engaged in an act of loving God above all else. This is the ideal mode of fulfilling the commandment of love, and it is also the end to which the commandment is intended to lead. But it is only in heaven, where God will be all in all (I Cor., xv. 28), that this ideal fulfillment will take place.

(b) Habitually, one loves God with one’s whole heart when one is in the state of grace, preferring the love of God to every contrary love, although it is only at intervals that one is able to make acts of love. This is the essential mode of fulfilling the command of love here on earth. The whole heart must be given to God to the exclusion of love for any mortal sin, for mortal sin separates from God.

The mode of loving God is expressed in various places in scripture (Deut., vi. 5; Matt., xxii. 37; Mark, xii. 30; Luke, x. 27), and there are slightly different interpretations given to the words by which it is conveyed. Thus, some exegetes see in the expressions “heart,” “soul,” “mind,” “strength,” synonymous significations of the one thought that God should be loved over all, and they think that different words are used only in order to give greater clearness and energy to the thought. But the following seems also a reliable explanation: (a) God must be loved with one’s whole heart, that is, the will must not intend any Last End other than God; (b) God must be loved with one’s whole mind, soul and strength, that is, the powers moved by the will—intellect, appetites and executive faculties—must be subject to God, must be regulated according to His will, and must carry out His commandments.

Love of God with one’s whole heart excludes, then, opposite loves, but it does not exclude other loves that are not opposite or other dispositions that are less perfect. (a) Thus, love of God with one’s whole heart does not exclude love of self or of neighbor. (b) Love of God with one’s whole heart does not exclude the use of acts in reference to God that do not reach the height of disinterested love, such as acts of hope, gratitude, or fear (see 1033, 1054, 1093).

There are various degrees of perfection in the fulfillment of the commandment of love of God.

(a) The most perfect fulfillment is found in heaven, where there is no turning from the love of God by grave sin, no impediment to its exercise by venial sin, and no interruption of its act by other occupations.

(b) The more perfect fulfillment of this commandment found on earth is modelled on the love of God exercised by the Saints in heaven, and the nearer one approaches to the model, the better does one fulfill the commandment. Thus, he who avoids not only what is against charity (i.e., mortal sin), but also, as far as possible, what is aside from charity (i.e., venial sin), loves God more perfectly than one who is careless about venial sin; and he who shuns, not only things unlawful that are harmful to charity, but also things lawful that interrupt the exercise of charity, loves God more, other things being equal, than another who avoids the unlawful, but whose mind is greatly occupied with lawful temporal matters.

(c) The ordinarily perfect fulfillment of the commandment is found in all those who, both in their internal and in their external acts, avoid all that is contrary to the love of God, although they fall into venial sin and are mostly occupied with temporal affairs. Thus is charity the bond of perfection (Col, iii. 14), the tie that binds man to his highest good; those who keep the commandments for its sake are followers after perfection, those who embrace counsels for its sake are in the state of perfection.
