Church visible is a term of Christian theology and ecclesiology referring to the visible community of Christian believers on Earth, as opposed to the Church invisible or Church triumphant, constituted by the fellowship of saints and the company of the elect.
In ecclesiology, the Church visible has many names, such as Kingdom of God, Disciples of Christ and People of God. St. Ignatius of Antioch was one of the first Christian authors to write about the subject, insisting that the Church visible was centered around the Bishop and the Eucharist or Last Supper. 
In early Christianity, anti-Gnostic and anti-Arian writers such as Irenaeus and Cyprian of Carthage would often focus on the visible Church in order to oppose various opinions deemed heretical. It was in this context that the expression Extra Ecclesiam nulla salus came about, which heavily insisted on the non-distinction between the visible and invisible Church. 
In the context of contemporary pluralism, there have been theological currents that downplay the role of liturgy and the public role of Christianity in order to remove it to the private sphere. Church leaders have responded by re-asserting the public, social and political character of the Church.
