Your subtitle is good. What I have a problem with is the body of your message which seems to be about the history of marriage with reference to the twenty fourth session of the
Council of Trent.
I don't see reference to morality, charity or evolution. I can only assume you are replying to a specific post, but it is not clear. If that is the case, then you might find that the little blue/green reply button on the post you are replying to will clear that up.
Marriage is tangentially related to the topic, so you haven't gone off the wall, I understand - just a friendly bit of advice for keeping our threads tidy and focussed. To be honest, if you are interested in the topic, it would make a fantastic discussion in its own right - you could propose a new topic on it.
