Easter [and Christmas and weddings and funerals] are occasions when Chreasters are present in worship. These CEOs [Christmas, Easter and Other] are people who primarily attend worship around Christmas and Easter. They are the underchurched. They are not inactive, but they are close.
On these occasions is a time to engage in authentically addressing needs they may have. This does not mean calling them out. It does mean mentioning some positive qualities of an active relationship with God and a Christian community. Talk about small groups and other programs being offered to help people deal with spiritual and social formation.
