A Voice from the Past - Anselm

We do no injustice or dishonor to God, but give him thanks with all the heart, praising and proclaiming the ineffable height of his compassion. For the more astonishing a thing it is and beyond expectation, that he has restored us from so great and deserved ills in which we were, to so great and unmerited blessings which we had forfeited; by so much the more has he shown his more exceeding love and tenderness towards us. For did they but carefully consider bow fitly in this way human redemption is secured, they would not ridicule our simplicity, but would rather join with us in praising the wise beneficence of God. For, as death came upon the human race by the disobedience of man, it was fitting that by man’s obedience life should be restored. And, as sin, the cause of our condemnation, had its origin from a woman, so ought the author of our righteousness and salvation to be born of a woman. And so also was it proper that the devil, who, being man’s tempter, had conquered him in eating of the tree, should be vanquished by man in the suffering of the tree which man bore. Many other things also, if we carefully examine them, give a certain indescribable beauty to our redemption as thus procured.

Can God's plan of salvation be accused of being too simplistic? What can be said in answer to this?
