Explanation:
Christian Church is an ecclesiological term referring to what different Christian denominations conceive of as being the true body of Christians or the original institution established by Jesus. It has been used in academia as a synonym for Christianity as well.
For many Protestant Christians, the Christian Church has two components: the church visible, institutions in which "the Word of God purely preached and listened to, and the sacraments administered according to Christ's institution", as well as the church invisible—all "who are truly saved" (with these beings members of the visible church). In this understanding of the invisible church, "Christian Church" (or catholic Church) does not refer to a particular Christian denomination, but includes all individuals who have been regenerated. The branch theory, which is maintained by some Anglicans, holds that those Churches that have preserved apostolic succession are part of the true Church. This is in contrast to the one true church applied to a specific concrete Christian institution, a Christian ecclesiological position maintained by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox churches, Assyrian Church of the East and the Ancient Church of the East.
The Christian Church originated in Roman Judea in the first century AD/CE, founded on the teachings of Jesus of Nazareth, who first gathered disciples. Those disciples later became known as "Christians"; according to Scripture, Jesus commanded them to spread his teachings to all the world.
