Church members have long debated whether to move the congregation, originally founded on the Near West Side in 1897, from the home built in 1965 for what’s now the second-oldest Greek Orthodox congregation in the country. Membership was around 500 families when the school moved and became a separate nonprofit more than a decade ago. And Jonas said it had slipped to about 125 families when he came to the church about 18 months ago — but despite financial uncertainty, the numbers have started to recover, reaching 170 families now.
