I too wonder about the authority aspect of this.
One of the major arguments many denominations under the Evangelical umbrella have against Rome is that centralized authority is not necessary above the pastoral level to follow the Word properly and to interpret scriptures correctly. In many denominations, matters of doctrine are voted on by pastoral electors, who have been led individually by the Holy Spirit to the correct interpretation. There may be a small group heading up the synod, but with little actual authority to issue manifestos of belief short of the pastors getting together and voting on doctrine.
If there is a central authority issuing things like this- doesn’t that defeat the point? At that level, you might as well have a magisterium and Papacy- at least they claim their authority by biblical/historical evidence; they are not just random committees making up dogma.
IMO, it really undercuts the idea that the Holy Spirit moves individuals locally at the pastoral level to the truth, and props up the idea that the Church must have some central authority to define broad dogmatic issues. And if there’s a central authority, the idea of apostolic succession is paramount, because otherwise you just have a random committee issuing edicts with no biblical or historical basis for doing so.
I sometimes wonder if it’s because of things like this that the idea of strict apostolic succession came out of the early church. It just seems like a committee like this is ripe for theological abuse, especially one that claims to be inter-denominational among all Evangelicals.
Just kind of troubling to me, seeing this kind of stuff, even if the theology of it is pretty vanilla protestant ideas.
