We ought to love one another seriously
It is the Lord’s will that our response to His love should not bring us away from our brothers and sisters; on the contrary, it should bring us closer to one another. Faith in the love of God vanishes when charity vanishes.
We should love one another seriously, with a love that is supernatural; we should love one another generously and faithfully, with a love that is not just words and feelings, but one that involves a real commitment to be patient and understanding with one another, a commitment to esteem and to help one another.
