Not all Christian jargon is good, but today I heard about 'speaking Jesus', which I think is great!
But perhaps you think it is just bad grammar. After all, how can you 'speak Jesus'? You can understand how to speak 'about Jesus', or 'to Jesus', but not simply 'speak Jesus'.
Jack Kilcrease has recently commented on postmodernism. He says it could be described as 'provisionalism' because it teaches that all representation of reality is provisional because it is not the thing it represents. So, the sign (e.g. the word 'tree') can never wholly convey the thing signified (e.g. the tree itself). However, Lutherans teach that by the promise of God the thing signified could be 'in, with and under' the sign. That is not the case with everything, but if God promises then he will perform the miracle.
The language of 'in, with and under' comes from the teaching that Christ is really present in the Lord's Supper. But you could also say the same about Baptism, and the words of absolution.
The same thing could then be applied to the Bible. It is not just about Jesus, but Jesus is really present when it is read. Similarly, when I speak faithfully about Jesus he is there with us. That's how I understand Matthew 18; Jesus is present when two are three are gathered because, and only because, of the words spoken. In this sense the Bible doesn't simply contain the Word of God in parts, but is the Word of God.
This can also be applied to the Church. Christ is 'in, with and under' the Church, so that it really is the Body of Christ and when you persecute the Church you persecute Christ (Acts 26:14).
This is all achieved by the Father sending the Spirit to create a mystical union.
I don't claim to understand Barth (perhaps Dan B could help me out), but I've always been struck by hearing that he taught that "God is his revelation", so there is no God other than the God who is Jesus Christ. Mike Reeves at NWA showed from Ezekiel and elsewhere that "God is his glory", or more specifically God the Father's glory has the name Jesus Christ. It is a bit mind-bending, and I think the language of 'in, with and under' (which, probably not coincidentally, are the words Paul uses for our union with Christ) are more helpful because the identification is not strict (otherwise Barth would be a Christomonist and I would believe that the Christ is the worldwide Church).
Does that make sense to people?
It could probably do with a lot more meditation and definitely a better written post than I have time for today, but I think I may adopt that lovely bit of Christian jargon: 'Speak Jesus to people'.
