- marriage is awesome enough to warrant active effort in dating if one is called to marriage, but not at all costs
- standards can be good, even if it means staying single
- no shame or moral inferiority in being single, regardless of age
- marriage almost always should be with another catholic
- no premarital sex or cohabitation
- dating is for finding future spouse, but there's not too much rush in determining whether or not someone is that future spouse
- relatively wide variety in how long a couple dates before deciding to marry
- normal to date in high school, but some people are against it, and some actively encourage it
Edit: i forgot to mention agape
I didn't limit to only what's specific to Catholics. Also, I've heard that Mormons think it's a big deal to still not be married at a certain age because it affect which level of Heaven you enter.
