Why turkey has the same name as Turkey
"belief that God and the universe are identical," from pantheist (n.), which was coined (1705) by Irish deist John Toland (1670-1722), from Greek pan- "all" (see pan-) + theos "god" (see Thea).
Toland's word was borrowed into French, which from it formed panthéisme (1712) which returned to English as pantheism "the doctrine that all is god" in 1732 (no evidence that Toland used pantheism).
Greek pantheios meant "common to all gods" (see pantheon). Other words used at various times for similar notions include panentheism, "philosophy founded on the notion that all things are in God" (1874), from German (1828), coined by Karl Christian Friedrich Krause (1781-1832).
The belief that God, or a group of gods, is identical with the whole natural world; pantheism comes from Greek roots meaning “belief that everything is a god.”
