The phrase "and the son" (''filioque'' in Latin) was first used in Toledo, Spain in 587 without the consultation or agreement of the [[Pentarchy|five patriarchs]] of the [[Church]] at that time and in direct violation of [[canons]] of the [[Third Ecumenical Council]] that prohibited unilateral alteration of the Creed by anything short of another [[Ecumenical Council]]. The purpose of its addition in Spain was to counter a [[heresy]] that was local to that region, probably some form of [[Arianism]]. The practice spread then to France where it was repudiated at the Gentilly Council in 767. Emperor [[Charlemagne]] called for a council at Aix-la-Chapelle in 809 at which Pope [[Leo III of Rome|Leo III]] forbade the use of the filioque clause and ordered that the [[Nicene-Constantinopolitan Creed]] be engraved on silver tablets displayed at St. Peter's Basilica in Rome so that his conclusion would not be overturned in the future. The dispute over the filioque clause and the manner of its adoption was one of the reasons for the [[Great Schism]]. The filioque clause was officially added to the Roman Catholic version of the creed by the Second Council of Lyons in 1274 , one of the two councils where Orthodox and Catholics reunited, although it was first used in liturgy during the coronation of Holy Roman Emperor Henry II by Pope [[Benedict VIII of Rome]] in 1014.
