Context

“It would not seem praiseworthy to enter religion without taking counsel of many, and previously deliberating for a long time. For it is written (1 John 4:1) : "Believe not every spirit, but try the spirits if they be of God." Now sometimes a man's purpose of entering religion is not of God, since it often comes to naught through his leaving the religious life; for it is written (Acts 5:38, 39) : "If this counsel or this work be of God, you cannot overthrow it." Therefore it would seem that one ought to make a searching inquiry before entering religion. Obj.” source
