All pastors know that there are legions of "Easter Christians" who make it their tradition to dress up once a year and touch base with God.

What can pastors do? Not much, said the late, great church-management guru Lyle Schaller, while discussing these red-letter days on the calendar. Rather than worrying about that Easter crowd, he urged church leaders to look for new faces at Christmas.

The research he was reading said Christmas was when "people are in pain and may walk through your doors after years on the outside," he said, in a mid-1980s interview. Maybe they don't know, after a divorce, what to do with their kids on Christmas Eve. Maybe Christmas once had great meaning, but that got lost somehow. The big question: Would church regulars welcome these people?

"Most congregations say they want to reach out to new people, but don't act like it," said Schaller. Instead, church people see days like Easter and Christmas as "intimate, family affairs … for the folks who are already" there, he said, sadly. "They don't want to dilute the mood with strangers."

It was classic Schaller advice, the kind he offered to thousands of congregations during his decades as a physician willing to work with bodies of believers -- if they were willing to admit they had problems. Ask him about Easter and he would talk about Christmas, if his research pointed him in that direction.
