If I am not wrong, it is not a catholic church. U looking for a catholic church?? Irene, one of the forumer here provided this link, u can go check it out.
My personal favourite is St Teresa still. Church of the St Mary Angels also veri nice. There's a new church at Pasir Ris, Divine Mercy, Not been there b4 so not sure how it looks like.
I have a list of church for rental. Maybe you can leave me your email address, I forward to you. My list was done 2 years back but I believe it still helps. Btw, when is your wedding date?
