Is there wedding ceremonies conducted during Advent season? if so, (or for any other time) what would be the process to have a wedding at this church? (we are currently not a member there)

Please feel free to call the church office and they will put you in contact with the wedding coordinating team.

You can also call the church directly and they can give you advice. I don't think they do weddings during advent but thats decided by the pastor.

You should call Tom or Sue Clain. They are the ones taking care of this ministry. Find their contract info here https://www.sfxphx.org/marriage-prep
