"While Sunday gatherings of the church are important, they are an incomplete experience of what the New Testament describes as church. It is impossible to carry out Paul’s “one another” instructions to the church in the context of an hour and a half on a Sunday morning. Therefore, we need some kind of structure to facilitate loving one another, bearing one another’s burdens, encouraging one another, forgiving one another, forbearing with one another, weeping with those who weep and rejoicing with those who rejoice."
