It is reductive simply to consider whether or not an individual’s actions correspond to a general law or rule, because that is not enough to discern and ensure full fidelity to God in the concrete life of a human being. I earnestly ask that we always recall a teaching of Saint Thomas Aquinas and learn to incorporate it in our pastoral discernment: “Although there is necessity in the general principles, the more we descend to matters of detail, the more frequently we encounter defects… In matters of action, truth or practical rectitude is not the same for all, as to matters of detail, but only as to the general principles; and where there is the same rectitude in matters of detail, it is not equally known to all… The principle will be found to fail, according as we descend further into detail”.347 It is true that general rules set forth a good which can never be disregarded or neglected, but in their formulation they cannot provide absolutely for all particular situations. At the same time, it must be said that, precisely for that reason, what is part of a practical discernment in particular circumstances cannot be elevated to the level of a rule. That would not only lead to an intolerable casuistry, but would endanger the very values which must be preserved with special care.348
For this reason, a pastor cannot feel that it is enough simply to apply moral laws to those living in “irregular” situations, as if they were stones to throw at people’s lives. This would bespeak the closed heart of one used to hiding behind the Church’s teachings, “sitting on the chair of Moses and judging at times with superiority and superficiality difficult cases and wounded families”.349 Along these same lines, the International Theological Commission has noted that “natural law could not be presented as an already established set of rules that impose themselves a priori on the moral subject; rather, it is a source of objective inspiration for the deeply personal process of making decisions”.350 Because of forms of conditioning and mitigating factors, it is possible that in an objective situation of sin – which may not be subjectively culpable, or fully such – a person can be living in God’s grace, can love and can also grow in the life of grace and charity, while receiving the Church’s help to this end.351 Discernment must help to find possible ways of responding to God and growing in the midst of limits. By thinking that everything is black and white, we sometimes close off the way of grace and of growth, and discourage paths of sanctification which give glory to God. Let us remember that “a small step, in the midst of great human limitations, can be more pleasing to God than a life which appears outwardly in order, but moves through the day without confronting great difficulties”.352 The practical pastoral care of ministers and of communities must not fail to embrace this reality.
In every situation, when dealing with those who have difficulties in living God’s law to the full, the invitation to pursue the via caritatis must be clearly heard. Fraternal charity is the first law of Christians (cf. Jn 15:12; Gal 5:14). Let us not forget the reassuring words of Scripture: “Maintain constant love for one another, for love covers a multitude of sins” (1 Pet 4:8); “Atone for your sins with righteousness, and your iniquities with mercy to the oppressed, so that your prosperity may be prolonged” (Dan 4:2427Relatio Finalis 2015, 14. 34); “As water extinguishes a blazing fire, so almsgiving atones for sins” (Sir 3:30). This is also what Saint Augustine teaches: “Just as, at the threat of a fire, we would run for water to extinguish it… so too, if the flame of sin rises from our chaff and we are troubled, if the chance to perform a work of mercy is offered us, let us rejoice in it, as if it were a fountain offered us to extinguish the blaze”.353
