Here are resources explaining the concept of a House Church, there history, why they are needed, and how to start at House Church.
Dear Reader I exhort each of you seek God's Spirit and guidance in these matters and resist the desire to follow after mans pattern of churches and be not deceived by those who seek to spiritually dominate over others.
Remember, Gods true church is: Jesus Christ and Born Again Believers having the indwelling of the Holy Spirit Our True Teacher, Our True Guide, Our True Comforter, God's Written Word and the Testimony of Creation.

Does this mean that God does not recognize or accept sincere Believers who attend mans churches ?
Does this mean God cannot use mans fallen churches for His own purpose ? No.
However, we should not continue attending or supporting mans fallen churches of which we have been forewarned to flee.
