how many fellows Emmanuel Swedenborg`s church had ?

Answer 1

As an educated estimate, not very many, and possible drawn from the more educated and mystically inclined. William Blake the great English poet/artist was influenced by Swedenborg`s thinking, (Blake`s father was a devotee of Swedenborg and his pseudo-scientific mysticism) and his work displays this influence. Swedenborg I believe, claimed the second coming had occurred sometime around 1750? The Church of The New Jerusalem which was founded after his death is still extant, now divided, one group of Swedeborgians claim direct inspiration from the `second coming`. In England, followers of Swedenborg are rare.

not very many
