Invite a priest to come to one of your meetings to talk about confession and then make themselves available for confession after.  This provides a special intimacy with the Sacrament.  If you do this, be sure to find a priest that is very inviting and one that your group will trust.  Because this provides such an intimate environment you may youth that would be very uncomfortable if they felt like that had to go to Confession and would rather go behind the screen or to someone that they don’t know.
