I haven't read the whole thread, apologies.
The church is very bad at talking about what baptism/marriage actually are.
As a result people who don't know much about Christianity, and perhaps a lot of Christians too, make a lot of assumptions about what they are. Almost everyone on this thread thinks that a marriage/baptism is (or should be) a proclamation of faith, a statement of belief, made in public, a kind of party political broadcast about what you believe, taking a platform to proclaim something. Therefore that anyone who struggles with the form of wording used, or who doesn't go to church regularly, is being a hypocrite.
However, this is a wrong understanding of what marriage and baptism actually are.
Baptism and marriage are "sacraments", in church speak. That means, they are a created opportunity for an encounter with God's grace, a sign of God's grace.
The person "doing the doing" at a baptism/marriage is GOD, not the bride/groom/parents/godparents. We are merely receiving something, i.e. God's grace and blessing on our marriage, our child etc. This blessing and grace is freely given, and is not conditional upon saying the right words or believing the right things.
In any event, the form of words used in these services are human-derived - put together by church elders at some ancient theological conference. They are not necessarily anything to do with God, although they are of course our attempt to say something about our understanding of God (which will always be limited - how can we humans understand that which is inherently transcendent?).
When I was baptised (as an adult) I looked upon the form of words as an important link with the traditions and history of the church that I was joining. I didn't think it was necessary to tick a box next to each statement that I 100% believed in it. It was enough that I felt a strong desire to be baptised and learn more.
Faith is a journey into deeper spiritual understanding. Baptism is the start of that journey. How can you be a fully fledged christian at the point of baptism? Baptism is only the beginning, God's grace being given to you freely and unconditionally to sustain you in that journey. Faith is like exercise - you start small and build up - no-one can run a marathon on day one. You also have to make the effort to maintain your spiritual fitness levels. If you don't bother going to church/praying/ or whatever it is that you do to sustain your faith, your faith will become weaker. Baptism happens at the point where the runner is beginning the Couch to 5k app, just running a tiny bit then walking! But if you keep it up, soon you will be running 5k without stopping.
So I think, if people want to be baptised/have their child baptised/get married in a church, then the fact that they want to is sufficient. Who are we to make judgements about why they want to? Most people don't want to
just because "its a pretty building" etc - they have a feeling that there is something important about it for them, even though they can't really articulate that and certainly wouldn't dream of going to church each sunday.
They aren't hypocrites in my book.
