In July 1708, Whiston wrote to the archbishops of both Canterbury and York, urging reform of Church of England doctrine in view of the false teaching of the Trinity as reflected in the Athanasian Creed.
Juulis 1708 kirjutas Whiston nii Canterbury kui ka Yorgi peapiiskopile ja õhutas neid reformima anglikaani kirikut, pidades silmas kolmainsuse väärõpetust, nagu seda esitab Athanasiose usutunnistus.
