Catena Aurea · Matthäusevangelium 26
And, behold, one of them which were with Jesus stretched out his hand, and drew his sword, and struck a servant of the High Priest’s, and smote off his ear. Then said Jesus unto him, Put up again thy swdor into his place: for all they that take the sword shall perish with the sword. Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels? But how then shall the Scriptures be fulfilled, that thus it must be?
(cont. Faust. xxvii. 70.) That is, every one who uses the sword. And he uses the sword, who, without the command or sanction of any superior, or legitimate authority, arms himself against man’s life. For truly the Lord had given commandment to His disciples to take the sword, but not to smite with the sword. Was it then at all unbeseeming that Peter after this sin should become ruler of the Church, as Moses after smiting the Egyptian was made ruler and chief of the Synagogue? For both transgressed therule not through hardened ferocity, but through a warmth of spirit capable of good; both through hatred of the injustice of others; both sinned through love, the one for his brother, the other for his Lord, though a carnal love.
