One more point that can be addressed here with regard to the Redemption and Christ's sole role in it.
So, one can say, that while many essential factors played a part in the Redemptive work, which is still ongoing, only the Blood Letting of Jesus Christ is the factor that separates Him from the rest of the co-redeemers.
Therefore: Christ's Blood == Fruits of Redemption
BTW: Blood is very Incarnational and from what I understand, Christ shed EVERY DROP of His BLOOD.
Then, came the Waters of Baptism, without which no one can be saved, in any form or fashion.
Desire alone being salvific is semi-Pelagian, and heretical as well as Protestant.
Water coupled with desire is ancient Roman Catholicism and thus, God ordained.
