Christ's true passion
Now, He suffered all these things for our sakes, that we might be saved. And He suffered truly, even as also He truly raised up Himself, not, as certain unbelievers maintain, that He only seemed to suffer, as they themselves only seem to be [Christians]. And as they believe, so shall it happen unto them, when they shall be divested of their bodies, and be mere evil spirits.
