7 In order therefore that we might learn, that whatsoever things Christ endured, for us and for our salvation He suffered them in reality and not in appearance, and that we also are made partakers of His sufferings, Paul cried with all exactness of truth, For if we have been planted together with the likeness of His death, we shall be also with the likeness of His resurrection. Well has he said, planted together. For since the true Vine was planted in this place, we also by partaking in the Baptism of death have been planted together with Him. And fix your mind with much attention on the words of the Apostle. He said not, “For if we have been planted together with His death,” but, with the likeness of His death. For in Christ's case there was death in reality, for His soul was really separated from His body, and real burial, for His holy body was wrapt in pure linen; and everything happened really to Him; but in your case there was only a likeness of death and sufferings, whereas of salvation there was not a likeness but a reality.
