This article analyses the ongoing relevance of the Canons of Nicaea to our approach to clergy discipline today. The article undertakes a comparative analysis, examining the application of the Nicene canons to church discipline from the perspective of both Eastern and Western traditions. The articles concludes with an overview of the new Clergy Conduct Measure 2025 and identifies areas that warrant further ecumenical study and partnership.

48 For example Canon 357 ascribes every cleric to a unit of jurisdiction within the territorial boundaries of the relevant patriarch. Canons 359–366 govern transference to another eparchy. Canon 374 requires clergy to ‘excel in the virtue of chastity’, whether single or married. Canons 385 and 386 deal with the use of temporal goods, restrictions on civil employment and the requirement for consent if leaving the eparchy.

58 Article XX1: ‘General Councils may not be gathered together without the commandment and will of Princes. And when they be gathered together (forasmuch as they be an assembly of men, whereof all be not governed with the Spirit and Word of God), they may err, and sometimes have erred, even in things pertaining unto God. Wherefore things ordained by them as necessary to salvation have neither strength nor authority, unless it may be declared that they be taken out of holy Scripture’.

62 The Rubric to the Ordinal in the Book of Common Prayer provides: ‘If any great crime or impediment be objected, the Bishop shall surcease from ordering that person, until such time as the party accused shall be found clear of that crime’. 28 Hen VIII c 21 Ecclesiastical Licences Act 1533/4, s 3 grants to the Archbishop of Canterbury, his commissary or deputy, power to grant dispensations previously granted by the See of Rome. The diocesan bishop may dispense under Canon C4 para 1, but only in respect of other crimes. Applications are made via the Faculty Office of the Archbishop of Canterbury; the Master of Faculties (a senior ecclesiastical judge) and a bishop make a report to the Archbishop. For a few years after the Reformation, dispensations were still required for physical and moral incapacities: see D Chambers, Faculty Office Registers 1534–49 (Oxford, 1966), xlii–xlviii. A ‘capacity’ was also required for religious dispossessed in Henry’s dissolutions to be released from vows and, in the case of a man, the capacity might enable the holder to hold a benefice for which a secular priest was eligible.

With the Shepherd’s love, they are to be merciful, but with firmness; to minister discipline, but with compassion …’; cf. Canon C18 para 7: ‘Every bishop shall correct and punish all such as be unquiet, disobedient, or criminous, within his diocese, according to such authority as he has by God’s Word and is committed to him by the laws and ordinances of this realm’.
