"So then the Lord Jesus, after he had spoken to them, was raised up into heaven, and is now seated at the right hand of God." Christ's body was glorified at the moment of his Resurrection, as shown by the supernatural properties it consequently and permanently enjoys. However throughout the forty days when he eats and drinks familiarly with his disciples and teaches them about the kingdom, his glory remains veiled under the appearance of normal humankind. Jesus' last apparition ends with the permanent entry of his humanity into divine glory, signified by the cloud and by heaven, where he is seated from that time forward at God's right hand. Only in a completely exceptional and unique way would Jesus show himself to Paul "as to one untimely born", in a last apparition that established him as an apostle.
At the Last Supper with his apostles on the eve of his passion Jesus anticipated, that is, both symbolized his free self-offering and made it really present: “This is my Body which is given for you” (Luke 22:19), “This is my Blood which is poured out...” (Matthew 26:28) Thus he both instituted the Eucharist as the “memorial” (1 Corinthians 11:25) of his sacrifice and instituted his apostles as priests of the new covenant.
