1599. Obligation of the Act of Love of God at the Close of Life.—The duty of making an act of love of God when one is at the point of death is admitted by all for the following cases: (a) the dying person is directly obliged to make an act of love of God when this is the only way in which he can secure justification, as when he is not in the state of grace and cannot receive the Sacraments; (b) the dying person is indirectly obliged to make an act of love of God when otherwise he cannot securely struggle against temptations to despair, doubt, etc.
1600. The duty of making an act of love of God at the time when death is near is considered as doubtful by some authorities when the following points are morally certain: (a) when the dying person has already sufficiently complied with the duty of making an act of love (e.g., when he made such an act just before he fell into danger of death), or is now in the state of grace (e.g., when he has received absolution with attrition just before or after the danger); and also (b) when the dying person will not expose himself on account of omission of the act of charity to the violation of any serious commandment.
1601. In practice, the priest who is attending the dying person should act as follows:
(a) He should remind the dying person of the obligation, if it appears certain, and should suggest to him the motives and assist him in pronouncing the form. In many manuals of the Ritual exhortations and aspirations suitable for this purpose are given.
(b) The priest should recommend the act of love of God, even though the obligation does not appear certain, if no harm will result from his doing so. For this will better prepare the dying person for entrance into eternity.
(c) He should not speak of the act of love of God, if the obligation is uncertain and harm would result from his doing so (e.g., if the dying person is in good faith, and would be much disturbed if told about the act of love to be made).
1602. Thus far we have spoken of the obligation which the precept of love of God imposes directly, or by reason of charity itself. There is also an obligation that is indirect, or by reason of some virtue or commandment distinct from charity.
(a) Thus, by reason of a virtue distinct from charity, one is bound to make an act of love of God, if this act is the only means of avoiding sin against that virtue. Example: Titus suffers severe temptations to injustice, and finds that only the love of God keeps him from injustice. In temptation, therefore, he should make an act of love of God.
(b) By reason of a commandment distinct from that of charity, one is bound to make an act of love of God, if otherwise one cannot fulfill rightly the commandment in question. Thus, if a person has to receive or administer a Sacrament of the living, or solemnly to administer a Sacrament, when he is not in the state of grace and has not the opportunity of receiving absolution, he is obliged to make an act of perfect contrition, which includes an act of love of God.
1603. An implicit love of neighbor is contained in every true act of love of God (see 1549, 1586). But in some cases love of neighbor must be explicit (see 1589).
