Origen

And observe that it is not said,’ He began to say,’ or ‘to teach,’ but to shew; for as things are said to be shewn to the sense, so the things which Christ spake are said to be shewn by Him. Nor indeed do I think, that to those who saw Him suffering many things in the flesh, were those things which they saw so shewn as this representation in words shewed to the disciples the mystery of the passion and resurrection of Christ. At that time, indeed, He only began to shew them, and afterwards when they were more able to receive it, He shewed them more fully; for all that Jesus began to do, that He accomplished. He must needs go to Jerusalem, to be put to death indeed in the Jerusalem which is below, but to rise again and reign in the heavenly Jerusalem. But when Christ rose again, and others were risen with Him, they no longer sought the Jerusalem which is beneath, or the house of prayer in it, but that which is above. He suffers many things from the elders of the earthly Jerusalem, that He may be glorified by those heavenly elders who receive His mercies. He rose again from the dead on the third day, that He may deliver from the evil one, and purchase for such as are so delivered this gift, that they be baptized in spirit, soul, and body, in the name of the Father, and the Son, and the Holy Spirit, who are three days perpetually present to those that through them have been made children of light.
