Ecclesiola in Ecclesia

"That Christians are not to conform to the world is a familiar concept of the New Testament. It is not so well known that Jesus also saw (and foresaw) the worldliness of the church itself and called his followers not to conform to the nominal church either, but rather to be a truly Christian community distinct in its life and practice from the religious establishment, an ecclesiola (little church) in ecclesia." -John R.W. Stott, The Message of the Sermon on the Mount
