Boris Johnson is a bigamist

... and the Roman Catholic Church is complicit.

In our Chalcedonian tradition, confiteor unum baptisma in remissionem peccatorum. If you are married in a schismatic tradition, you are still married in the Christian tradition. Unless you are a Monophysite or Vox Day or, I dunno, a Jew.

Yes I know; muh 'nnulment process, yadda yadda. Annulment's unideal but traditionally the Church may grant it if there came no viable children from the union. Bigamous Boris, of course, has spawned several.

Honestly even if you're Jewish you shouldn't be divorcing and marrying again under another roof. It's not even the Creeds at issue here but Jesus' exegesis of the Torah - which was shared by the Essenes, and by the Prophets. G-d has joined man and woman, not man and woman and woman. To the extent Lilith be a thing (she shouldn't be a thing) we are really getting into apocryphal weeds if we posit children from that union.
