The Church Walks Away From the Death Penalty & Trial by Ordeal: 4th Lateran Council (1215 Anno Domini)

CANON 18

"No cleric may pronounce a sentence of death, or execute such a sentence, or be present at its execution. If anyone in consequence of this prohibition (hujusmodi occasions statuti) should presume to inflict damage on churches or injury on ecclesiastical persons, let him be restrained by ecclesiastical censure. Nor may any cleric write or dictate letters destined for the execution of such a sentence. Wherefore, in the chanceries of the princes let this matter be committed to laymen and not to clerics. Neither may a cleric act as judge in the case of the Rotarrii, archers, or other men of this kind devoted to the shedding of blood. No subdeacon, deacon, or priest shall practice that part of surgery involving burning and cutting. Neither shall anyone in judicial tests or ordeals by hot or cold water or hot iron bestow any blessing; the earlier prohibitions in regard to dueling remain in force."
