A few Sundays ago in church, I sat listening to my pastor when I noticed something wonderfully peculiar. An elderly couple sitting a few pews ahead of me caught my eye; at first glance, it appeared they had one mutual arm. I wasn’t sure where one arm began and the other ended. This may seem a mere trick of the eye, but I saw something more. In fact, I witnessed a representation of marriage as I saw a joining of two people. They were so close to one another that it seemed they shared more than a name, more than a past, more than even love itself – they shared their very lives, right down to the limb. I wonder how it must be to be so much a part of someone else and to have a virtually mutual existence.
