So over the last few years I've known a lot of young Christian couples who've got married at about 21-23 years old. The classic situation is Christian boy and girl meet at the CU at uni and then get married when they graduate. Obviously part of this is the belief that couples shouldn't have sex before they are married but I think another factor is that they have prayed through and considered their decision to get married and trust that if it is the right decision they should just go ahead and get married. There seems often to be a critical and confused response to this idea of getting married from non-Christians so I was interested to see the mumsnet response. I suspose the idea of waiting for sex and getting married young is something that a lot of couples did in the past and many of us have grandparents or perhaps parents who married young and have had very long (and in most cases) marriages.
