“One is the body of the church, whose head is Christ, and all cohere in it. We [the pope] vicariously administer His power and preside over others by His will. You [the bishops] and We [the pope] are the more prominent members of the same body. For, what can happen to individual members which does not affect all or pervade each? Accordingly, whatever concerns you concerns Us, and vice versa. Therefore, together we must all labor for the health and safety of the church, so that, without blemish or strain, it may flourish. With God’s help we can accomplish this if each of you is enkindled by as strong a zeal for his flock as possible and if your one concern be to remove from his flock all contagion of evil and pitfalls of error and to strengthen it diligently with all the aids of sound doctrine and holiness.”  Pope Clement XIV, Cum Summi, December 12, 1769, Par. 3
