The Wedding Party
It is expected that the members of the wedding party will conduct themselves at all times in a manner acceptable to a place of worship. No alcoholic beverages are allowed in the church or on the church grounds. Members of the wedding party are also expected to refrain from using alcoholic beverages immediately prior to the rehearsal and wedding. The wedding rehearsal or wedding will not be performed if any member of the wedding party is under the influence of alcohol. Smoking is not permitted in the building. It is the responsibility of the bride and groom to communicate these policies to the wedding party.
You may want to provide your wedding party and family with an agenda and time schedule of your rehearsal and wedding day activities, so all involved will know what is expected of them.
