Question: My fiancé and I will be getting married next fall. We would like to write our own wedding vows. We will be getting married in a Catholic Church and someone told me that there are certain words that need to be said if you are writing your own vows. Can you tell me what certain things have to be said in our vows? Answer: Yes, it is fine to compose your own wedding vows. The formula should include all the required elements in the procedure: 1) that the other person is being accepted as husband or wife. 2) that each will be faithful to the other. 3) that the marriage is lifelong.
