...Thou hast written concerning the meeting of His Highness Christ after the crucifixion and that some of the apostles perceived Him but did not recognize Him; but that they did recognize Him after the breaking of bread.
Know thou that the Messianic Spirit and the outpouring of the Holy Spirit is always manifest, but capacity and ability (to receive it) is more in some and less in others. After the crucifixion the apostles had not in the beginning the capacity and ability of witnessing the Messianic reality. For they were agitated. But when they found firmness and steadfastness, their inner sight became opened, and they saw the reality of the Messiah as manifest. For the body of Christ was crucified and vanished, but the Spirit of Christ is always pouring upon the contingent world, and is manifest before the insight of the people of assurance.
