Just this past Sunday, my son was christened. Or Baptised. It really depends on who you are, and what you call it.
I got into a discussion with my Father-in-law about how it was always called a "Christening" when he was growing up, but now it is called a Baptism". Technically, the event could be called either in the case of an infant, but they aren't exactly interchangeable.
Both my parents, and myself to a point were brought up Baptist. To the baptist denomination, Baptism is something that can only be done by an Adult. Only once someone has come of age, and is doing so of their own free will.
Currently, my wife and I attend a Methodist Church. (Actually, we both joined this Sunday... Figured as long as we are going in front of the congregation, may as well kill 2 birds with one stone, so to speak.) The methodist Church believes in Infant Baptism. However, a Christening is not merely a baptism. As I found out with some reading in the past few days, Christening is also a dedication. The Idea is that a child is dedicated to "Christendom", or the Christian Faith, in much the same way a ship or church was historically dedicated when it was christened.
Anyway, it was a beautiful service. We actually had my whole family and a large chunk of my wife's family all together under the same roof. My son Logan, all dressed in white. He acted perfectly during the service, and it almost brought tears to my eyes. I know these days, a lot of people aren't very big on these kinds of ceremonies, but It is a very meaningful one to my wife and I.
