The first ecumenical council of the Church, the Council of Nicaea focused on Jesus' Incarnation. A heretic named Arius was teaching people that Jesus wasn't fully divine. People were confused about this and other teachings, so the Council of Nicaea was held. One of the results of this council is the Nicene Creed. It is a list of Catholic beliefs so people wouldn't be so confused, but will be officially applied later on.
The second council of the Church, the Council of Constantinople, was called to settle some remaining problems from the Council of Nicaea and also some new ones. This council disproved the teachings of Arianism, clarified the ways that the Trinity was described, and sharpened the differences of the Eastern and Western branches of the Church.
