Synod of Oxford

[2] It was a council of the (Catholic) church in England, convened by Archbishop Stephen Langton.

[11][12] Langton's ambition was to reform the English church, especially with regard to monastic law.

[13] The Synod also followed and implemented the anti-Jewish decrees laid out by the Fourth Lateran Council of 1215.

[7] For many centuries, it was thought that the Synod set the celebration of 23 April as Saint George's Day on a par with other Christian feast days, although it stopped short of declaring St George the patron saint of England, which did not happen until 1347.

[7] In May 2022, to mark the 800th anniversary of the Synod, a service was held at Christ Church Cathedral, Oxford.
