67 The Only-begotten God suffered indeed all that men can suffer: but let us express ourselves in the words and faith of the Apostle. He says, For I delivered unto you first of all how that Christ died for our sins, according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures. This is no unsupported statement of his own, which might lead to error, but a warning to us to confess that Christ died and rose after a real manner, not a nominal, since the fact is certified by the full weight of Scripture authority; and that we must understand His death in that exact sense in which Scripture declares it.
In his regard for the perplexities and scruples of the weak and sensitive believer, he adds these solemn concluding words, according to the Scriptures, to his proclamation of the death and the resurrection. He would not have us grow weaker, driven about by every wind of vain doctrine, or vexed by empty subtleties and false doubts: he would summon faith to return, before it were shipwrecked, to the haven of piety, believing and confessing the death and resurrection of Jesus Christ, Son of Man and Son of God, according to the Scriptures, this being the safeguard of reverence against the attack of the adversary, so to understand the death and resurrection of Jesus Christ, as it was written of Him.
There is no danger in faith: the reverent confession of the hidden mystery of God is always safe. Christ was born of the Virgin, but conceived of the Holy Ghost according to the Scriptures. Christ wept, but according to the Scriptures: that which made Him weep was also a cause of joy. Christ hungered; but according to the Scriptures, He used His power as God against the tree which bore no fruit, when He had no food. Christ suffered: but according to the Scriptures, He was about to sit at the right hand of Power.
He complained that He was abandoned to die: but according to the Scriptures, at the same moment He received in His kingdom in Paradise the thief who confessed Him. He died: but according to the Scriptures, He rose again and sits at the right hand of God. In the belief of this mystery there is life: this confession resists all attack.
