“Confirmation is a beginning, not an ending.” I say it a gazillion times over the course of the year, from the introductory meeting with parents to the presentation of the confirmands to the congregation.
Saying it is doesn’t make it so, though. I think there is something else that needs to be said to make the statement more of a reality.
“See you next week.”
Even better, “See you at youth group next week” or “See you at choir next week” or “See you in worship next week” or see-you-at-anything-the-congregation-does next week. Like, right away.
Maybe it helps to have a concrete next step.

We can help! As a congregation, we should be saying not just “Welcome,” but also “See you next week” — or “I go to (blank); would you like to try it?”
