Like others have said, baptism by either denomination would still be a Christian baptism...and given that 'baptism' is the key word here, it shouldn't matter if it's an Anglican or Uniting one (IMO).

However, if your DH doesn't even attend his denominational church, out of principle I would have the baptism done at your church, spesh since you'll be the one taking your child(ren) to church. Why is he concerned with it being Uniting when he doesn't even attend?! Can he explain his rationale? What does he classify as a 'Christian' and Christian community? If he's not living that way.........why?

On the other hand, if it's going to cause ugly disagreements...well, at the end of the day your baby is still baptised before God's eyes....who is God of both the Anglicans and Unitings! The Bible has no denominations listed so why should we?! Man made rules!

Hope I haven't offended you with any of this....but I think it's important for you DH to give some decent reasons for his Uniting bent. Just because he might have been baptised Uniting doesn't mean that's the best reason for his child to be. If he was going to take him/her to a Uniting church and bring them up in that specific doctrine, well, I wouldn't worry about your children being baptised Uniting...but if he's not willing to do that, I kinda don't see why he's so concerned.....would be hypocritical (augh! sorry if that offends you) of him to demand a baptism his style.

Pray about it! Talk to God about it......pray for your husband to come to a compromise with you....pray that God will soften his heart and given him understanding of where you are coming from......prayer always works best for me

ps: what sort of wedding ceremony did you have?
