“[Thomas Aquinas] says that the very least one of these sufferings was of itself suffering enough to redeem the human race from all sin (that is woven into the Adoro Te). But, says St. Thomas, it was fitting that He should have to endure all at once. One suffering would have sufficed for our Redemption, but it would not suffice for the Love of the Redeemer. He meant to give copious Redemption. He willed that the beaker should brim over. He gave a thousand Redemptions all in one.”
