A Latin word meaning "and the Son."
Western churches began adding this word to the Nicene Creed several centuries after it was written: "I believe In the Holy Spirit . . . who proceeds from the Father and the Son."
This "filioque clause"
is judged by the Orthodox Church as error because it is contrary to what Jesus taught (John 15:26)
; thus, it confuses correct belief concerning the Holy Trinity. The addition of the filioque in the West was a major factor contributing to the Great Schism, A. D. 1054.
