35 Just here zeal out of place and without discretion may easily become the cause of real disaster. Call to mind one of the most memorable facts of sacred history. Certainly neither courage, willingness, nor devotion to the sacred cause of religion were lacking in those priests who gathered round Judas Maccabeus, to fight with him against the enemies of the true God, the profaners of the temple, the oppressors of their nation. And yet, releasing themselves from the rules of discipline, they rashly engaged in a combat in which they were vanquished. The Holy Spirit tells us of them "that they were not of the race of those who might save Israel." Why? Because they would obey only their own inspirations, and threw themselves forward without awaiting the orders of their leaders. "In die illa ceciderunt sacerdotes in bello, dum volunt fortiter faccre, dum sine consilio exeunt in praelium.(25) Ipsi autem non erant de semine virorum illorum, per quos salus facto est in Israel. "(26)
