In my church (The Church of Jesus Christ of Latter-Day Saints), we have sacred ordinances that we do in temples. When a young man or woman reaches the age of 12, they have the opportunity (if they live worthily), to attend the temple and do an ordinance that we call, Baptisms for the Dead. This ordinance gives people who have died the opportunity to be baptized and receive the gospel on the other side. This is the only ordinance in the temple that the youth can participate in. Once they are older (usually after the age of 18), they are able to go through the temple for other ordinances.
I used my Scripture HeroeZ and a template from Simple Scrapper
