(1) Not all Baptists believe eternal security. (2)
There are other denominations which believe eternal security. (3)
This has not traditionally been counted as a Baptist distinctive.
These are the reasons I don't include it.
Honestly, I've gotta say that in terms of Baptist distinctives believer's baptism by immersion is really the one I would stick to the most. It is one of the principle reasons whhy I've stayed Baptist during my journey. (There are other reasons)
I don't see how, when one considers NT theology, you can come up with another option for believers. Though I respect other traditions, believer's baptism is a standard and practice which I believe is both NT and historical. When we look at the early church that is the pattern (there is a bit of infant baptism going on but that is not consistent.)
Every born-again believer has direct access to the throne of God. Therefore, since every child of God shares in the priesthood of the believers, all have the same right as ordained ministers to communicate with God, interpret Scripture, and minister in Christ's name. This is first and foremost a matter of responsibility and servanthood, not privilege and license.
Two that are twins:
Regenerate, Immersed Church Membership
Immersion of Believers and Lord's Supper the Only Two Ordinances.
(Though, I can go along with foot washing.)
I have three that I would miss terribly -- I can't narrow it to just one. The three are:
autonomy of the local church; individual soul liberty; priesthood of the believer. These all seem intertwined.
About autonomy:
I believe that the local church should be able to do as they feel led without any person or group of people outside interfering -- even if I think that local church is grievously wrong.
Other denominations believe in and practice autonomy, and some may actually have more soul liberty than Baptist churches, but I don't know of any other denomination which believes in the priesthood of the believer like the Baptists do.
Anyway, I have been a member of two denominations other than Baptist, and I have worshiped in almost every denomination to be found in these parts, but none compare to the Baptist distinctives.
My views are very diverse, encompassing elements of several denominations, but mostly my core beliefs, which I cherish, are decidedly Baptist, and those I mentioned are the ones I cherish the most and would be the hardest to give up.
I was going to say "believer's Baptism" because that is probably the ONLY baptist distincive that ALL baptists on this board would agree with.
We all would probalby agree with the ones you listed here, but would define them in different ways.
That said, I might put local church autonomy above believer's baptism for this reason:
I think I could easily and with a clear consience attend a church that practiced believer's baptism, but which also accepted as members those who were fully convinced that their prior Presby or Methodist infant Baptism was a true and valid baptism.
I attended a non-denominational church that held that position for 2 years.
(they could only do that due to their local church autonomy).
That said, I have this question for you:
Is the CAC a single church, or an association...and if it is an association of several local churches...how do they have autonomy if there is a CAC statement of beliefs (like about homosexuality, for example) that CANNOT BE CHANGED).
does that no infringe on each local assembly's autonomy to decide for themselves on that issue, or ordaining women?
The CAC is a young communion, and I admit the polity is experimental; probably nothing like it exists or has existed before. I also can see how it could be rather messy, for the reasons you stated. So far, it has not been, but I can see how it could be.
I would say that the CAC is both a single church and an association. Our ministers affirm the Statement of Principles. They voluntarily join, but part of that is affirmation of the Principles. If at any time they find themselves in disagreement where there is not liberty of conscience allowed -- as in homosexual unions or ordinations -- they understand that they have voluntarily taken themselves out of the Communion. The same with congregations. Also, the CAC name is protected by a Service Mark, whereby if another group wanted to call themselves Celtic Anabaptist and practice apostate Christianity, they would have to come up with some variation on the denominational name. Is that authoritarian? Some would say so. But I am determined to protect traditional ethics; that's why these matters are not subject to vote, like the mainline Presbyterians and Episcopalians have done.
As for ordination of women, this is an area where the local congregation could decide. We ordain women; that's in our Principles, but we would not force a local congregation to do so. If they didn't believe in it, that's their business.
So, we believe in and practice liberty of conscience on most doctrinal matters, but not so much on moral and ethical matters. We have a communion-wide Statement of Principles with liberty in their use, except for traditional moral values which we will not compromise. We have some hierarchy, but in the Celtic-relational sense, not the Catholic. So, we combine an episcopal structure with a congregational structure with local church autonomy -- the best of the ancient Celtic church and Baptist/Anabaptist heritage.
