Some provinces of the Anglican Communion have been reticent about restoring the vocational diaconate. The most frequent objection is that ordained deacons clericalise lay ministry and in any case lay people can do anything that deacons can. Also, bishops and priests are already deacons, so a separate order is redundant.
But part from ignoring the historical roots of the diaconate, this approach negates the purpose of ordination. Deacons are officially commissioned to a leadership role by the Church, to which they make a lifetime commitment. A leading deacon in the US-based Episcopal Church, Susanne Watson Epting, has put it this way: “Even though ordained, [the deacon’s] primary identity remains baptismal and our ordination charges and vows serve only to expand, enhance, and urge us on in animating and exemplifying the diakonia to which all the baptised were called.” Experience with the renewed diaconate has amply fulfilled this assertion.
As for bishops and priests already being deacons, there are those, including myself, who turn the argument on its head. The Church should return to its original practice, end sequential ordination and abolish the transitional diaconate, which serves little purpose and inhibits the ministry of the vocational deacon. Food for thought!
