when was the first vatican council held and what two topics were discussed
First Vatican Council The council was convoked to deal with the contemporary problems of the rising influence of rationalism, liberalism, and materialism.[4] Its purpose was, besides this, to define the Catholic doctrine concerning the Church of Christ.[5] There was discussion and approval of only two constitutions: the Dogmatic Constitution on the Catholic Faith and the First Dogmatic Constitution on the Church of Christ, the latter dealing with the primacy and infallibility of the Bishop of Rome.[5] The first matter brought up for debate was the dogmatic draft of Catholic doctrine against the manifold errors due to rationalism.[6]
Council of Jerusalem The Council of Jerusalem or Apostolic Council was held in Jerusalem around AD 50. It is unique among the ancient pre-ecumenical councils in that it is considered by Catholics and Orthodox to be a prototype and forerunner of the later ecumenical councils and a key part of Christian ethics. The council decided that Gentile converts to Christianity were not obligated to keep most of the Law of Moses, including the rules concerning circumcision of males. The Council did, however, retain the prohibitions on eating blood, meat containing blood, and meat of animals not properly slain, and on fornication and idolatry, sometimes referred to as the Apostolic Decree or Jerusalem Quadrilateral.
