Jesus is just a word I use to swear with.
I don’t think Jesus was an exclusivist. He said, and we believe, that He is the unique representation of God in the world. But that doesn’t mean this is the only way God can work.
The righteousness of Jesus Christ is one of those great mysteries, which the angels desire to look into, and seems to be one of the first lessons that God taught men after the fall.
The basic question ‘will I obey Christ ‘s teaching?’ is rarely taken as a serious issue. For example, to take one of Jesus’ commands, that is relevant to contemporary life, I don’t know of any church that actually teaches a church how to bless people who curse them, yet this is a clear command.
