The Council of Jerusalem, the first Church Ecumenical Council, set the tone for how the Church resolves difficult decisions. Do Christians need to be circumcised? Abstain from meat with blood in it? The Council of Jerusalem, the 15th Century Council of Florence (Basil) and even Trent, Vatican I and Vatican II are legacies of the first council recounted in Acts and Galatians. "‘It is the decision of the Holy Spirit and of us..." Words that have guided the Church to the present time.
