We heard a little addendum to the sermon at church yesterday about love and about how we shouldn't judge the way others love. I think that was the point of the addendum, but I can only speculate (and would probably be wrong) as to why it was offered on the Sunday of the Cross, when we are so clearly shown in the liturgy what love is and what it looks like.
But if one cannot deduce from the language of the liturgy for that particular day of the church year what love really is and how we are to love one another, it's also quite clearly outlined here in 1 Corinthians:
If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing. If I give away all I have, and if I deliver my body to be burned, but have not love, I gain nothing. Love is patient and kind; love is not jealous or boastful; it is not arrogant or rude. Love does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrong, but rejoices in the right. Love bears all things, believes all things, hopes all things, endures all things.
This particular passage wasn't cited in the addendum, it (and anything that even sounded remotely like it) was noticeably absent, actually. But I believe that it's still a good gauge for us to use when we contemplate our own actions and relationships with others. And while the point of the addendum was (I think) about how we shouldn't judge the way others love, I think that when it concerns us - how we are to love and how we are loved by others - we need such a gauge if we are to determine whether the love we show others or the love that is shown to us is of God or not.
