How would you handle important events for friends and family with which you disagree with the concept or correctness of the ceremony? Does it make a difference if the event is important to a child or an adult? Perhaps you even find the event sinful. Specific examples or general rules are welcome.

Here are some potential situations:

• Infant’s baptism for a credobaptist (does it make a difference whether it is Reform, Lutheran, or other?)
• "Second" baptism for a paedobaptist
• First Communion for someone who isn’t Catholic
• Woman’s ordination for a complimentarian
• A divorced person’s wedding while their first spouse is still alive
