Thirteenth century England was a dicey place for theological heterodoxy.
an apostate deacon, who for the love of a Jewess had circumcised himself. When he had been degraded he was burnt by the servants of the lord Fawkes.
The story of this nameless and foreskinless deacon — and the link includes several congruent descriptions from primary sources — is sometimes conflated with that of Robert of Reading, another Christian divine who converted in the late 13th century.
Robert’s fate — or Haggai’s, to use the new name he took — seems to be officially unknown, and might have unfolded overseas: Edward I expelled Jews from England in 1290. Nevertheless, the mixed Robert-anonymous deacon story was commemorated with a plaque at Osney Abbey.
Whomever this date’s deacon really was, he wasn’t the only one for whom this council ordained a dreadful end for having the wrong idea about the Almighty.
And there was brought thither into the council an unbelieving youth along with two women, whom the archdeacon of the district accused of the most criminal unbelief, namely that the youth would not enter a church nor be present at the blessed sacraments, nor obey the injunctions of the Catholic Father, but had suffered himself to be crucified, and still bearing in his body the marks of the wounds had been pleased to have himself called Jesus by the aforesaid women. And one of the women, an old woman, was accused of having long been given to incantations and having by her magic arts brought the aforesaid youth to this height of madness. So both being convicted of this gross crime, were condemned to be imprisoned between two walls until they died. But the other woman, who was the youth’s sister, was let go free, for she had revealed the impious deed.
