Guy Muse has an excellent article on "What does Scripture actually say about the church, the Bride of Christ?"
He writes:
One of the most common questions I am asked in church planting training is: at what point do we start taking the new believers to church? This question always frustrates me, but I understand the paradigm struggle many face with house churches being "real churches."
The response I am tempted to give is, "what I hear you asking is at what point do we stop making disciples, and allow them to just start attending church services?" Of course, I bite my tongue before saying this, but it reflects the difficulty we have of understanding the who, what, when, where, and why of the true nature of the New Testament ekklesia.
