The New Church in the Midst of the Old.

On the day of Pentecost as an outcome of the coming-down of the Holy Ghost and the preaching of the apostle Peter, a new congregation, or church visible, (as seen by man) was gathered and began to worship and "break bread" in the midst of the old church visible (Judaism, the temple) which had rejected and crucified the One sent to her. But the true church, which is indefectible, is known only to God - it is invisible to man; for the Lord knows who are His and "let everyone who names the Name of the Lord depart from iniquity" (2 Timothy 2: 19).
