The High Feast of Pentecost

“The king stablished all his knights, and gave them that were of lands not rich, he gave them lands, and charged them never to do outrageousity nor murder, and always to flee treason; also, by no mean to be cruel, but to give mercy unto him that asketh mercy, upon pain of forfeiture of their worship and lordship of King Arthur for evermore; and always to do ladies, damosels, and gentlewomen succor upon pain of death. Also, that no man take no battles in a wrongful quarrel for no law, ne for no world’s goods. Unto this were all the knights sworn of the Table Round, both old and young. And every year were they sworn at the high feast of Pentecost.”

-Sir Thomas Malory

When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.

-Acts of the Apostles

Then anon they heard cracking and crying of thunder, that them thought the place should all to drive. In the midst of this blast entered a sunbeam more clearer by seven times than ever they saw day, and all they were alighted of the grace of the Holy Ghost. Then began every knight to behold other, and either saw other, by their seeming, fairer than ever they saw afore.... Then there entered into the hall the Holy Greal covered with white samite, but there was none might see it, nor who bare it.... And then the king yielded thankings to God, of His good grace that he had sent them. Certes, said the king, we ought to thank our Lord Jesu greatly for that he hath shewed us this day, at the reverence of this high feast of Pentecost.

-Sir Thomas Malory

It was on Pentecost that the Holy Grail went about in the world, leading the knights out from Camelot to their destruction in quest of God's truth. It was on Pentecost that the apostles, likewise keeping together in safety and company, were set afire to go out into the world to quest.

Of the knights who went on that quest few returned again to Camelot. For a long time I thought that was a warning against seeking too much after a perfection that was not meant for human kind.

But of the apostles, almost all were martyred: all but John.
