Sure. Jesus Himself says so. Allow me to show the relevant speech:
Matthew 19:
[3] And there came to him the Pharisees tempting him, and saying: Is it lawful for a man to put away his wife for every cause?
[4] Who answering, said to them: Have ye not read, that he who made man from the beginning, Made them male and female? And he said:
[5] For this cause shall a man leave father and mother, and shall cleave to his wife, and they two shall be in one flesh.
[6] Therefore now they are not two, but one flesh. What therefore God hath joined together, let no man put asunder.
Not: Two men. Not: Two women.
“For this reason God made male and female.” Cleave together–one flesh. Whom GOD has joined together.
That is marriage.
Do some people degrade marriage? Sure they do. Some men and women do not marry with the intent to ‘stay married’. Some marry from ‘love’ and then when the bloom is off the rose, hurry on to the next person they feel ‘love’ for. So?
We have many moral concepts and laws that express an ideal, including "Love God with your whole heart, soul, mind and strength’ and "love your neighbor as yourself.’
Can you tell me if ANYBODY in the world routinely and perfectly obeys those two commands? All the time? I don’t think so.
But are we going to change them around and say that Christ didn’t mean them? Or that it’s perfectly all right to ignore what He said and make Christian teaching into something more ‘tolerant’ like, “Love God at home or in Church however you feel ‘right’, love your neighbor but only the way you want, when you want, and only those you want to BE your neighbor” and then claim we’re following Christ’s teachings in a better way?
Again, I don’t think so.
