who sponsored a council of bishops which reaffirmed the nicene creed
Nicene Creed The third Ecumenical Council (Council of Ephesus of 431) reaffirmed the original 325 version[31] of the Nicene Creed and declared that "it is unlawful for any man to bring forward, or to write, or to compose a different (ἑτέραν) faith as a rival to that established by the holy Fathers assembled with the Holy Ghost in Nicaea" (i.e., the 325 creed). The word ἑτέραν is more accurately translated as used by the Council to mean "different", "contradictory", rather than "another".[32][32] This statement has been interpreted as a prohibition against changing this creed or composing others, but not all accept this interpretation.[32] This question is connected with the controversy whether a creed proclaimed by an Ecumenical Council is definitive in excluding not only excisions from its text but also additions to it.
Marriage in the Catholic Church With the development of sacramental theology, marriage was included in the select seven to which the term "sacrament" was applied. Explicit classification of marriage in this way came in reaction to the contrary teaching of Catharism that marriage and procreation are evil: the first official declaration that marriage is a sacrament was made at the 1184 Council of Verona as part of a condemnation of the Cathars.[38] In 1208, Pope Innocent III required members of another religious movement, that of the Waldensians, to recognize that marriage is a sacrament as a condition for being received back into the Catholic Church.[38] In 1254, Catholics accused Waldensians of condemning the sacrament of marriage, "saying that married persons sin mortally if they come together without the hope of offspring".[39] The Fourth Lateran Council of 1215 had already stated in response to the teaching of the Cathars: "For not only virgins and the continent but also married persons find favour with God by right faith and good actions and deserve to attain to eternal blessedness."[40] Marriage was also included in the list of the seven sacraments at the Second Council of Lyon in 1274 as part of the profession of faith required of Michael VIII Palaiologos. The sacraments of marriage and holy orders were distinguished as sacraments that aim at the "increase of the Church" from the other five sacraments, which are intended for the spiritual perfection of individuals. The Council of Florence in 1439 again recognised marriage as a sacrament.[38][41]
