I'll carry on drawing together some thoughts from others on unity in future posts, but here's something that's been buzzing around my head for a wee while on unity. What does it look like in practice to maintain unity in an interdenominational setting like a CU?
It occurs to me that there are two models.
The first model is a kind of 'lowest common denominator' approach. Speakers in this model are instructed to only present Biblical teaching that all members present can agree with (i.e. from within the Doctrinal Basis). If a speaker presents an issue outside of this band of core teaching (and if particularly they teach on a 'secondary' issue that falls outside of the Doctrinal Basis) they might be reprimanded or encouraged next time to focus on core issues (depending on the amount of graciousness shown by CU members). In the model, 'tolerance' is defined by limiting what might cause offence or discomfort. In practice I think this model often leads to the domination of whatever the most popular church background in the CU is.
It seems to me that a better approach would be a second model. In this model, speakers are encouraged to pitch their material bearing in mind that the CU is a short-term interdenominational mission team. However, when they believe that the passage or issue that they have been asked to speak upon requires teaching on a 'secondary issue', they feel free to teach it (albeit humbly bearing in mind that other evangelicals can also have Scripturally-driven positions that are different to their own). CU members bear in mind that within the CU setting, they agree to agree upon the core doctrines of the gospel (as summarised in the Doctrinal Basis) but agree to disagree upon secondary issues. Therefore, so long as the speaker is led by Scripture in their teaching of a secondary issue, they are willing to receive such teaching (even if it is very different from the position they themselves hold). In this model, 'tolerance' is defined by loving somebody as a brother or sister for whom Christ died, even when they hold a position of theology that is very different from your own. It is looking somebody in the eye and saying that you are glad they are part of a gospel-focused mission team with you (and saying this even if you might never join their church).
It seems to me that the second model is stronger than the first model, and closer to the Biblical model of unity than the first. It is harder to achieve, because it is requires a strong understanding of what CUs are about, and a thorough focus upon grace. But I think it is worth striving for.
I once remember a colleague speaking of how, ideally, each CU member should come away from a CU central gathering feeling slightly frustrated, because not everything was done in a way that matched their own preferences and positions of secondary doctrine. However, he said, in this sense of general dissatisfaction, there is great satisfaction - modelling together great unity in the gospel, and being more effective on campus as a group than a whole host of smaller groups ever could be by themselves.
