+I. The unity or oneness of the Church as set forth by the unity or oneness of the body.+--One life animates the whole. The parts mutually subserve one another, while the head thinks and the heart beats for all. There is a certain harmony existing between all the members; they constitute a symmetry among themselves, so that one could not be taken away without destroying the perfection of all the others, more or less marring the grace and beauty of the whole frame. So the Church is one--one mystical body--having one author, God; one Head, which is Christ; and one informing Spirit, the Holy Ghost; one country towards which all its members are travelling, heaven; one code of instructions to guide them thither, the Word of God; one and the same band of enemies seeking to bar their passage, the world, the flesh, and the devil. Despite all miserable divisions, wherever there is a man with true love to God and man, any true affiance on Christ, any true obedience to the Spirit and His leadings, _there_ exists a member of this mystical body. +II. As in the human body there is unity, so there is also variety, diversity, multiplicity.+--This is true of the Church of Christ. Its different members have different functions and offices, and in performing these the Church makes equable and harmonious growth. +Lessons.+--1. _As members of the same body, let us not separate from brethren in Christ._ 2. _If we are members one of another, many are the debts as such we owe the one to the other._ (1) We owe one another _truth._ (2) _Love_ one to another. (3) _Honour_ one to another.--_R. C. Trench._ Ver. 5. _One Lord._ +I. Christ is our Lord according to every notion and acceptation of the word "Lord."+--He is our Prince and Governor, we are His subjects and vassals; He is our Master, and we are His servants; He is our Owner, or the Possessor and Proprietary of us; He is our Preceptor or Teacher; that is, the Lord of our understanding, which is subject to the belief of His dictates; and the Lord of our practice, which is to be directed by His precepts. He is therefore also our Captain and Leader, whose orders we must observe, whose conduct we should follow, whose pattern we are to regard and imitate in all things.
