Maundy Dancing

The Acts of John, a Greek version of which was discovered at
Oxyrhynchus in the 1890s, could have been composed some time
in the second century,with some traditions holding that the Gnostic
chronicler Leucius Charinus was its author, although this attribution
isn’t certain. Leucius was said to have been a young disciple of
the aged St John, from whom he received secret teachings and
stories about Jesus. The Acts of John is an account of the activities
of the apostle in Asia Minor some time after the crucifixion, its most
celebrated passage being the so-called ‘Round Dance of the Cross’.
This scene takes the form of a sermon delivered by John to a crowd
of people, probably in Ephesus, where much of the Acts of John
takes place. John recounts the events of the night before Jesus was
arrested. In canonical accounts, Jesus prays in the Garden of
Gethsemane, but in the Acts of John, he instead commands them
to dance and respond with an ‘Amen’ to his praises to God:

He then began to sing a hymn, and to say:
‘Glory be to you, Father!’
And we circling him said, ‘Amen’
‘Glory be to you,Word! Glory be to you, Grace!’
‘Amen’ […]
We praise you, O Father.We give thanks to you, light, in whom
darkness does not abide.’
‘Amen.’

As the disciples continue to respond to Jesus, he begins to dance and
instructs them to do the same:

‘The whole universe takes part in the dancing.’
‘Amen’
‘He who does not dance, does not know what is being done.’
‘Amen’

Jesus’ hymn now becomes a series of paradoxes, stating that he will
flee and stay, adorn and be adorned, unite and be united.The hymn
ends with some beautiful mystical statements:

‘I am a lamp to you who see me.’
‘Amen.’
‘I am a mirror to you who perceive.’
‘Amen.’
‘I am a door to you who knock on me.’
‘Amen.’
‘I am a way to you, wayfarer.’
‘Amen.’

Jesus then encourages the disciples to understand the dance by
seeing him within themselves, which echoes the Gospel of Philip’s
statement that those who have achieved gnosis are ‘no longer a
Christian, but Christ,’ and also the Gospel of Thomas, in which
Jesus declares:

‘Whoever drinks from my mouth will become like me.
I myself shall become that person,
and the hidden things will be revealed to that one.'

The similarity with the mystery schools is made explicit in the very
next line, in which Jesus enjoins the disciples to ‘keep silence about
my mysteries!’ Jesus explains that, through the mystery of the
suffering that he is about to undergo, the disciples will have the
chance to become moved and, in doing so, will be ‘moved to become
wise…Learn suffering and you shall have the power not to suffer.’
