In conventional theology Jesus Christ takes the sins of the entire world - past, present and future - upon himself. Through his sacrificial death he achieves forgiveness for all sins; through his resurrection we are assured of eternal life. Since Jesus Christ is "fully God and fully human", the second person of the trinity, according to the orthodox position he can accomplish redemption: as God he has the power to do so and as man he stands for and includes all human beings in his saving death and life-giving resurrection. ....Almost had you going there, eh? According to McFague this is a theology that today, for North-American Middle-class Christians, is "not believeable and bad theology". It does not correspond to today's understanding of reality. This kind of theology, she says, puts the "offense of Christ in the wrong place", that is, it makes faith about a conflict with science rather than with a conflict with a sinful way of life.
Personally, I have never been able to believe it.

It is bad theology only from our particular perspective of course. It is bad because in this kind of Christology "Jesus does it all". It does not engage us in creation, it does not motivate us to get involved in the "project in which we join God in Christ to help all creature's flourish".
