102. Saint Thomas Aquinas explains that “it is more proper to charity to desire to love than to desire to be loved”;(Thomas Aquinas, Summa Theologiae, II-II, q. 27, art. 1, ad 2) indeed, “mothers, who are those who love the most, seek to love more than to be loved”.(Ibid., q. 27, art. 1)Consequently, love can transcend and overflow the demands of justice, “expecting nothing in return” (Lk 6:35), and the greatest of loves can lead to “laying down one’s life” for another (cf. Jn 15:13). Can such generosity, which enables us to give freely and fully, really be possible? Yes, because it is demanded by the Gospel: “You received without pay, give without pay” (Mt 10:8).
Demanded by the Gospel, it may be, but we are still human beings troubled by some aspects of this, especially when it touches on our own sense of fair play. For your reference, remember that Amoris Laetitia is online here.
