What word refers to the whole Christian church? liturgy faction ecumenical orthodox

The word that refers to the whole Christian Church is "ecumenical". Ecumenism represents the efforts of Christian Churches to develop closer relationships and visible, organic unity of different Christian denominations in some form. It is originally used in terms as "ecumenical council" and "Ecumenical Patriarch" which refers to totality of a larger Church rather than being restricted to one of its constituent local churches or dioceses.
