How does one respond to the arguments "love is love," and "how does it affect you?"
"Love" can have at least four (4) distinct meanings in Catholic spiritual understanding, over two radically different categories, namely
natural love, and
supernatural love.
1) pre-Christian love - this is totally self-centered attraction to that which gives personal gratification. "I love pizza!" "I love my new car!" "I love classical music and bluegrass!" And sadly, people can "love" other people in this same way: they "love" others to the extent that the other pleases them. If and when the other fails to please them, the "love" is no longer there. This kind of "love" can include that of "friendship" as well as erotic or sexual "love."
2) Something radically different is made possible in God's grace - supernatural, divine charity which is the love with which God loves, and which itself has three levels - or depths - or stages as the person grows, or matures, in the life of Christ. In Him - in Christ - we see the highest expression of love in His pure self
less love, His Self-gift on the Cross.
The Church holds, in her Sacrament of Holy Matrimony, the graces needed for this
perfection of love in the state of marriage. (This perfection is of that supernatural love first received sacramentally in Baptism, and can reach perfection either in the married or the single state.)
