The anomaly of the Roman Catholic Order of Friars Minor - the religious group founded by the peace-loving St. Francis of Assisi but split into three factions that have disputed for centuries who were his true followers - may be resolved soon.

A survey of the three groups has revealed that 70 percent of the 5,000 U.S. Franciscans, Conventuals and Capuchins believe that the time has come to combine the divisions of the worldwide order.

According to the Rev. Roy Gasnick, chairman of the survey committee, if members around the world feel the same way, the first steps toward unification of the order could be taken in 1982 during the common celebration of the 800th anniversary of the birth of St. Francis.
