Amazing. Christus Victor and related views are the orthodox view, these having been held for the first thousand years of the church. Penal substitution has only been held since Calvin. So, which one is really outside the "bounds of orthodoxy"?
PS can in no sense then be said as necessary Christian doctrine to be held, nor any of the other johnny-come-lately interloping atonement doctrines.
You people really need to study scripture and the early church -- you know that same scripture that the early church recognized as the canon and from which it got its doctrines, of which PS was nowhere to be found.
WHICH early church though? Has the Church shortly after Apsotle John started having those wolves coming into the fold, and advocating things like baptism regeneration, pre souls existing, Church replaced israel etc...
Look to the bible and Apostolic doctrines, not early Church fathers!
