A quick question for one such as myself who is a little confused on one point: I can see why they might want to commission deaconesses, but what is the purpose of not continuing to ordain male deacons? That really turns the issue on it's head for me.
Keep in mind most of the few churches that have deaconesses, especially those that came from the RPCES
do ordain Deacons in accordance with the BCO and have their "deaconesses" under the authority of the [Board of] Deacons.
Where these churches are out of accord with our BCO, is that, in some cases they are:
1) electing the "deaconesses"
2) "commissioning" them with the same or similar vows as ordination
3) not appointing men to also serve like this (as assistants to the deacons) per BCO 9-7.
In addition, there is no BCO warrant for the office "deaconess."
The (very) few churches that are
much farther out of accord are, in addition:
4) refusing to constitute a BCO Diaconate to govern in the church
Because they cannot ordain women (no presbytery would allow that) and have no mechanism to set the un-ordained group of mostly women in authority, they are de facto placing them as tactical governors of the church below the Elders (session). This, of course, is blatantly unconstitutional (BCO) and unbiblical.
Meanwhile, it seems the very few churches in the second category are mainly advancing generally "role of women" and "deacon is really only another name for servant" arguments, not BCO ambiguity. Churches in the first category of non-compliance do not seem to be making these two arguments.
Remember, the doctrinal understanding of the PCA, required by in the Book of Church Order, is that Deacons are part of the basic governing structure of each church.
Deacons are qualified by I Timothy 3 with un-ordained women and men assisting them in ministering mercy, liberality and property stewardship to each congregation of believers. This tends to result in Deacons leading in and overseeing mercy and all sorts of tactical operations of the church but involving a high level of lay people (both men and women) in the process. In my opinion, this is close to the biblical model and is a very good thing because it spreads out involvement for our Lord's work in these key areas, while clearly calling out the men God has equipped and called for the high office of Deacon.
