ANSWER: All along down the Christian ages there have been some theologians who have given an affirmative answer. They say that the incarnation was not contingent upon man's sin, but that it was the original purpose of God for the exaltation of the human race, promoting their highest spirituality and felicity. They, moreover, dislike the doctrine expressed by the "felix culpa" ("blessed be the sin") which brought God into man and man into God. To the writer the idea is very distasteful and repugnant, that sin has been beneficial to our race. Those interested in this question should read Bishop Westcott's essay, "The Gospel of Creation," in his commentary on the Epistles of St. John; 87 pages.
