Being practical, or just an opportunist?

A couple of days ago I read an article in Times about one of the latest decisions of the Church of England. From now on, unmarried couples who have a little baby and want to baptise it, can do it together with the ceremony of getting married. It's time saving, it's money saving, it definitely makes happy those, who do not think about a wedding until they find out that they will have a baby and want to baptise it.
And so what? Isn't this practical and useful change something that is totally against one of the core rules of the Church? How can people get married in Church while they are already having a baby? Should they confess their sins and, as required to be forgiven, regret all of them, including giving life to their newborn? Wouldn't that be a lie? That just doesn't make sense to me.
There are many voices of critism quoted in this article about the new liturgy. But, on the other hand, there is also a response from one of the priests, that he used to provide that kind of service before and there is nothing suprising in these changes...
Well, as usual, there are many perspectives to look from... Obviously, religion must acknowledge social changes, they are undeniable. And one of the most effective ways of gathering adherents is by answering people's needs, every kind of them. But I guess that there are some limits, and if they are crossed, the fundaments of religion, which are its truths and beliefs, can be dangerously interrupted.
It is difficult to decide what is more important in the end - the beliefs and rules, or the people. Changing rules can prove that religion is weak and dependant on people, but indeed, without people, religion would not exist.
More responses to the article appeared on the next days, written by those concerned whether it makes sense to baptise a little baby, when parents are not truly Christian (meaning: active believers and church-goers), as they most probably won't take care of religious education of the child. There are voices that maybe it would be better for a young person to make a mature, informed decision about their religious adhension later in life.
It is worth thinking about how social life changes and how the image of religion changes as well. I have so many examples in my head after readings for my last essay about Evangelicalism! :)
