Hi topbannana. Just to echo what everyone else says: it sounds as if you have a great church, and I think you should be grateful for that and enjoy it.
To try to answer your questions:
- We would not attend every week but would like to attend for major celebrations (if that is the correct word) I know other families who are not weekly attendees but would this be frowned on?
There are lots of people who don't get to church regularly for whatever reason. People will be happy that you are there when you're there (iyswim), and will definitely not worry about why you're not there at other times. Of course, it may grow on you and you may start wanting to be there more regularly... but that will be entirely up to you.
- Should DS be christened/ baptised or whatever is appropriate?
Your ds is not a baby, and so he should really make this decision for himself. It's not a problem that he hasn't been baptised already, so it will be for him to ask to be baptised if and when he chooses to do so. When infants are baptised their parents and godparents speak for them and make a series of promises on their behalf. When older children or adults are baptised, they make those promises for themselves. If your DS wants to be baptised, he - or you - could talk to the vicar and see what he suggests. They might feel that, given his age, he could be baptised and confirmed at the same time. Eight may be a bit young for confirmation (my dd was baptised and confirmed a couple of months ago and the youngest at that service was 7, but normally I get the sense that the CofE tends to confirm, say, 10s and above... though someone will correct me if I'm wrong).
As I say, my dd was baptised and confirmed recently (she's 10) at her own request. No-one ever asked me why she hadn't been 'done' as a baby or questioned her/my motivation. She did attend some preparatory lessons, which she enjoyed. She was baptised (along with a couple of others) right at the beginning of the service, and then confirmed alongside about 8 or 9 others later in the service. Like your ds she serves in church (she mostly acts as 'boat bearer' - quite 'high' church = lots of incense!!) and she started doing this before she was baptised.
We do go (me and her - my other dd and dh don't go near the place, sadly) most weeks now, but this has only been something we've started doing in the last couple of years (as I gradually moved from agnosticism to belief).
- Personally I like the supportive and welcoming atmosphere in church, as well as the being thankful for what we have bit. A lot of the heavy religious stuff passes over my head as I was never raised in that sort of situation and I do not understand it. Is it appropriate to attend church just to be grateful for my lot, rather than to understand and enjoy passages from the bible (I am worried I may seem a bit of a fraud for not having strong religious beliefs)
That sounds entirely appropriate to me. As others have said, you may start wanting to know and understand more, and if so there are ways of going around that, from having a quiet word with the vicar to attending a course to reading a book to talking to some of the very knowledgeable people on here.
Please don't feel a fraud. Even the people with the strongest and most enduring faith have doubts sometimes. You are there because you appreciate the church's message, because you want to support your ds, because you like to be part of the community that the church represents, perhaps a little bit because you want to find out more. That is a fantastic starting-point.
And if you don't move beyond that starting-point, I would suggest that you're still doing something that it central to the Christian faith, which is very much a faith of community. Jesus said that when two or three people gathered together in his name, he'd be there with them. So it seems to me that the fact of stepping over the threshold to attend a service is already quite meaningful, in that you are entering willingly into that community - a community of which Jesus himself is a part. (And if that last bit is a bit too 'God-botherer-ish', don't worry. Just enjoy being there and see what happens.)
Good luck.
