"There is a description of Christ in Nephi’s words: 'Wherefore, redemption cometh in and through the Holy Messiah; for he is full of grace and truth.' (2 Ne. 2: 6) We imagine that statement to mean He had all conceivable grace and all conceivable truth. It might instead mean His life was filled with such grace as was needed for it, and such truth as was required for it. Within His sphere and element, He attained perfection. But did He know calculus (to make an illustration)? Nothing indicates Christ had any need to know calculus. It wasn’t that He couldn’t learn it, of course, but it wasn’t required of Him." (The Second Comforter)
