It is always the dogma of the removal of guilt through representative substitution that shows most decisively whether an approach is merely anthropologically or truly christologically (that is, theologically) centred. Without this dogma, it always remains possible to interpret everything in rational terms as an expression of human possibility, no matter how much historical mediation one wishes to build in. Our inability to resolve this dogma into gnosis is the true scandal; it is a signal and a warning that this is where genuine faith begins.
