Conversion to Anglicanism and British citizenship
On 29 June 1927, Eliot converted to Anglicanism from Unitarianism, and in November that year he took British citizenship. He became a warden of his parish church, Saint Stephen’s, Gloucester Road, London, and a life member of the Society of King Charles the Martyr.[28][29] He specifically identified as Anglo-Catholic, proclaiming himself “classicist in literature, royalist in politics, and anglo-catholic [sic] in religion”.[30][31] About thirty years later Eliot commented on his religious views that he combined “a Catholic cast of mind, a Calvinist heritage, and a Puritanical temperament”
He was raised in a Unitarian church, and his grandfather was a Unitarian minister.
