Now a days, it is very common for couples to look for something different to say and do at the altar. If you are among these "innovative" couples, start by considering what is important to both of you; customize the proceedings to your own values and dreams! Be sure, however, to check with your officiant about rules and guidelines.
Here are some areas couples often personalize:
your officiant will most probably provide you with a list of recommended readings. Most of the readings should focus on some aspect of togetherness and marriage. If you have favorite passages you'd like to read, be sure to ask your officiant if it would be possible to include them in your ceremony.
Many couples feel very comfortable to bear heart and soul in front of other people. If this is your case, make sure you let your officiant know about your intentions. Some religions can be quiet strict about what vows must be said.
If you are not so comfortable with writing your own vows, but somewhat feel that the traditional vows lack intimacy, you might want to read a poem or a passage that expresses your feelings.
Most officiants request that the songs you select be religious in nature. This, however, does not mean you are restricted to music you'll hear only in a church. Try finding commercial songs that meet the criteria..you will be surprised!
