What all ceremonies should we include in our wedding... we are planning for church wedding and reception after that... as per hindu wedding we have function know as "Sagan" i.e. Ring exchange... can we do same in christian... I will appreciate if any one can guide me regarding christian wedding... thanks in advance

Yes

Yes there is a ring exchange during the ceremony, before you are announced husband and wife.

How to combine the Sagan, and the traditional Christian ring exchange in a church wedding, should be discussed with the official who is actually doing the ceremony.

I have seen 'blended' weddings with traditions from each of the bride and groom, and it is lovely to see both incorporated into the one ceremony.

You are doing sagai with him but there is lot to sagai just than ring exchange. There is small puja and gift and shagun exchange. So for the christine wedding, you can do ring exchange, breaking the glass ritual.
