The group scheduled a retreat for April 17 at the Saint Benedict Center in Schuyler, which is run by the Benedictine order.
Curtiss asked the Benedictines not to allow the retreat there.
A spokesman for Curtiss said the archbishop was worried that allowing Call to Action to meet on church-sponsored property would confuse people because the group advocates positions contrary to the church doctrine.
The retreat has been rescheduled for the same day at the Saint Thomas United Methodist Church in Omaha.
