There is a very evident tendency to stress the fact that the Church is a great missionary agency, and to forget that it is first of all the assembly of the saints, in which those who publicly live in sin cannot be tolerated. It is said that sinners must be gathered into the church, and not excluded from it. But it should be remembered that they must be gathered in as saints and have no legitimate place in the Church as long as they do not confess their sin and strive for holiness of life.Systematic Theology, 601
Weakness with watchfulness will stand, when strength with too much confidence fails. Weakness, with acknowledgement of it, is the fittest seat and subject for God to perfect his strength in; for consciousness of our infirmities drives us out of ourselves to him in whom our strength lies.
The Bruised Reed
We do not deny that the church has many functions in relation to the Scriptures. She is: (1) the keeper of the oracles of God to whom they are committed and who preserves the authentic tables of the covenant of grace with the greatest fidelity, like a notary (Rom. 3:2); (2) the guide, to point out the Scriptures and lead us to them (Is. 30:21); (3) the defender, to vindicate and defend them by separating the genuine books from the spurious, in which sense she may be called the ground of the truth (1 Tim. 3:15*); (4) the herald who sets forth and promulgates them (2 Cor. 5:19; Rom. 10:16); (5) the interpreter inquiring into the unfolding of the true sense. But all these imply a ministerial only and not a magisterial power.
The church is not a theological classroom. It is a conversion, confession, repentance, reconciliation, forgiveness and sanctification center, where flawed people place their faith in Christ, gather to know and love him better, and learn to love others as he designed.
When the church is absolutely different from the world, she invariably attracts it. It is then that the world is made to listen to her message, though it may hate it at first.
Christians do not stand isolated, each holding his own creed. They constitute one body, having one common creed. Rejecting that creed, or any of its parts, is the rejection of the fellowship of Christians, incompatible with the communion of saints, or membership in the body of Christ. In other words, Protestants admit that there is a common faith of the Church, which no man is at liberty to reject, and which no man can reject and be a Christian.
Certainly when we undervalue mercy, especially so great a one as the communion of saints is, commonly the Lord takes it away from us till we learn to prize it to the full value. Consider well therefore the heinousness of this sin, which that you may the better conceive. First, consider it is against God's express precept, charging us not to forsake the assemblies of the saints (Heb. 10:20, 25). Again, it is against our own greatest good and spiritual solace, for by discommunicating and excommunicating ourselves from that blessed society, we deprive ourselves of the benefit of their holy conference, their godly instructions, their divine consolations, brotherly admonitions, and charitable reprehensions, and what an inestimable loss is this? Neither can we partake such profit by their prayers as otherwise we might, for as the soul in the natural body conveys life and strength to every member, as they are compacted and joined together and not as dissevered, so Christ conveys spiritual life and vigor to Christians, not as they are disjoined from but as they are united to the mystical body, the church.
There are two great ends why Christ did institute a particular church, and they were to express the two great graces and duties that He requires of us. The first end was that his saints together might jointly profess their faith in Him and obedience to Him. And we have no other way of doing it: He hath tied us up to this... The next great end was that we might have a direct exercise of His other great command and of that other great duty, of love to believers.
A church is a company of those who are called (and this call must be answered or else it is nothing) to the visible profession of faith in Christ and obedience unto Christ, according to the gospel.
For the church is a company of men that are called (1 Cor. 1:24; 10:32), both Jews and Greeks, to the Jews, to the Greeks, and to the church of God. But because the end of calling is faith, and the work of faith is engrafting into Christ, and this union with Christ does bring with it communion with Christ. Hence it is defined, in the very same sense, a company of believers, a company of those who are in Christ, a company of those that have communion with Christ.
Let us not look so much who are our enemies as who is our Judge and Captain, nor what they threaten but what He promises; we have more for us than against us. What coward would not fight when he is sure of victory? None are here overcome but those that will not fight. Therefore, when any base fainting seizes upon us, let us lay the blame where it is to be laid.
We are weak, but we are His; we are deformed, but yet carry His image upon us. A father looks not so much at the blemishes of his child as at his own nature in him; so Christ finds matter of love from that which is His own in us. He sees His own nature in us. We are diseased, but yet His members. Whoever neglected his own members because they were sick or weak? None ever hated his own flesh. Can the head forget the members? Can Christ forget Himself? We are His fullness, as He is ours. Bruised Reed, 107
We are now by the Spirit at liberty to delight in the law, to make the law our counsellor, to make the Word of God our counsellor. That which terrified and frightened us before is now our direction. A severe schoolmaster to a very young pupil becomes later, as the pupil grows, a wise tutor to guide and direct. So, the law that terrifies and whips us when we are in bondage, till we are in Christ -it scares us to Christ -that law afterward comes to be a tutor, to tell us what we shall do, to counsel us and say this is the best way. And we come to delight in those truths when they are revealed to us inwardly. And the more we know, the more we want to know, because we want to please God better every day.Glorious Freedom, 41
Cast yourself into the arms of Christ, and if you perish, perish there. If you do not, you are sure to perish. If mercy is to be found anywhere, it is there.
