In a Christian gathering we often declare our allegiance, our vision and our commitment in some formal manner to commence our time together (some people call this a "service"; perhaps because we serve each other as per 1 Cor 14, although gathering/assembly/meeting are perhaps better words).
We might do this in the words of the Apostles Creed, a passage of scripture, or prayer.
My favourite scripture passage is (from the Morning Prayer format):
If we say that we have no sin, we deceive ourselves, and the truth is not in us: but if we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 1 St. John 1.8-9.
Of late some Christian gatherings start with intoning an 'acknowledgement of country'. Sometimes this is given an attempt of a buffer, packaging it with some Christian niceties. But this is false as we would not do the package if we weren't really doing the AoC.
In case you don't know, an AoC is intended to 'acknowledge' Aboriginal presence on this island prior to the arrival of multi-cultural refugees from Britain in 1776 or so. Noting this is already well done and honoured in endless adoption of Aboriginal place names across Australia.
The AoC itself is a type of ceremonial paean derived from one invented in the 1970s by an Australian Aboriginal entertainer, Ernie Dingo (BTW a very good entertainer!) at the behest of, I think, of a Maori group who did historically have such a greeting.
So what does recital of these words imply when done in some association with a Christian gathering of any type, in a church publication (newsletter, website, letter) or sign?
As one of my bosses told me many years ago (she was CEO of a professional society) when a board member wanted to do something similar. The boss lady supported my rejection of the idea because "we do not split our brand". That is, we do not represent ourselves as anything but ourselves. We do not confuse our market as to who we are. No offense implied or intended, but we are who we are, not someone else.
Aside from her commercial 'nose' and loyalty to the organization, she could see the diffusion of our allegiance to our mission being implied by acquiescing to the request.
Now, what happens in a church context?
Same thing: we 'split our brand'. No longer do we meet to edify one another in the Spirit, we also meet to 'acknowledge' on political (perhaps on faux or real or misplaced compassionate grounds) a formal non-Christian, indeed pagan belief structure with practices as diachronically ungodly as the Western heritage is.
Do we acknowledge the Ancient Greeks or Romans? Caesar, even Constantine? No. What about Boadicea, Nero, or Scipio Africanus? No. These would be completely incongruent with our faith.
It also degrades implicitly the faith of Aboriginal Christians as we overturn Paul's teaching in Galatians 3:28. All of a sudden there is 'Jew and Greek'! We have injured in our words the unity of the body of Christ. We have said we meet for other than our Christian mission of making disciples. We have confused our message in our now split brand, mixed our allegiance and denied our Lord. Instead of inviting the world in, we have asked to join it!
Let's stop doing it and get some backbone when questioned. We are no longer of this world: Aboriginal and non-Aboriginal Christians, we are all "in Christ". Thanks be to our Lord and Saviour.
