170:5.15

In this manner the kingdom became the concept of an age, the idea of a future visitation, and the ideal of the final redemption of the saints of the Most High. The early Christians (and all too many of the later ones) generally lost sight of the Father-and-son idea embodied in Jesus’ teaching of the kingdom, while they substituted therefor the well-organized social fellowship of the church. The church thus became in the main a social brotherhood which effectively displaced Jesus’ concept and ideal of a spiritual brotherhood.
