303. Recognizing the influence of such concrete factors, we can add that individual conscience needs to be better incorporated into the Church’s praxis in certain situations which do not objectively embody our understanding of marriage. Naturally, every effort should be made to encourage the development of an enlightened conscience, formed and guided by the responsible and serious discernment of one’s pastor, and to encourage an ever greater trust in God’s grace.
Conscience is not something to be formed while a believer struggles within a crisis. It seems that enlightenment is best engaged first when one is solidly and soundly in the light. Also, practice in small matters will develop fortitude and habit for more serious challenges.
Pope Francis mentions the importance of moving in stages. The Ignatian principle of magis comes to mind. While often attached to the over-achieving spirit people often see in Jesuits, I see it as more practical. One wise pastor I worked for often described his wish for parishioners, a gradualist approach to get involved more deeply one step at a time.
Yet conscience can do more than recognize that a given situation does not correspond objectively to the overall demands of the Gospel. It can also recognize with sincerity and honesty what for now is the most generous response which can be given to God, and come to see with a certain moral security that it is what God himself is asking amid the concrete complexity of one’s limits, while yet not fully the objective ideal. In any event, let us recall that this discernment is dynamic; it must remain ever open to new stages of growth and to new decisions which can enable the ideal to be more fully realized.
