Fidelity challenges us in a particular way today because its difficulty has come to be associated with it being something unnecessary or unnatural. In fact, love draws us into a kind of commitment. God Himself shows that this commitment is fully intended on His side and generally lacking on ours. Infidelity begins when our will commits to someone else from that place within our hearts that is reserved for one alone. The vow of chastity is not just the withholding of one’s body from the marital act: it is the consecration of all the affections of the heart to God. This doesn’t produce people who are frigid, but, for those who “can accept it,” they become by their devotion tangible sparks and flames manifesting the kingdom already present now. All are loved, not for themselves, but because God is loved above all.
