not the whole thought - Surnames

I got to thinking about surnames. I always thought I understood the sacrament better because of how when we are married we take our husband's name upon us. But, actually, this was and is not done in many countries. I suspect it was a Christian practice because of taking His name upon us, and in the Bible He being likened unto a bridegroom. I think I got it backwards. We as women, take a surname upon us as a tribute or replication in microcosm of the act of taking Christ's name upon us.
