Face plain facts. Anybody who is convinced that he belongs to Christ must go on to reflect that we all belong to Christ no less than he does. Maybe I do boast rather too much about our authority, but the Lord gave it to me for building you up and not for pulling you down, and I shall not be ashamed of it. I do not want you to think of me as someone who only frightens you by letter. Someone said, ‘He writes powerful and strongly-worded letters but when he is with you you see only half a man and no preacher at all.’ The man who said that can remember this: whatever we are like in the words of our letters when we are absent, that is what we shall be like in our actions when we are present.

  We are not being so bold as to rank ourselves, or invite comparison, with certain people who write their own references. Measuring themselves against themselves, and comparing themselves to themselves, they are simply foolish. We, on the other hand, are not going to boast without a standard to measure against: taking for our measure the yardstick which God gave us to measure with, which is long enough to reach to you. We are not stretching further than we ought; otherwise we should not have reached you, as we did come all the way to you with the gospel of Christ. So we are not boasting without any measure, about work that was done by other people; in fact, we trust that, as your faith grows, we shall get taller and taller, when judged by our own standard. I mean, we shall be carrying the gospel to places far beyond you, without encroaching on anyone else’s field, not boasting of the work already done. If anyone wants to boast, let him boast of the Lord. It is not the man who commends himself that can be accepted, but the man who is commended by the Lord.

  I only wish you were able to tolerate a little foolishness from me. But of course: you are tolerant towards me. You see, the jealousy that I feel for you is God’s own jealousy: I arranged for you to marry Christ so that I might give you away as a chaste virgin to this one husband. But the serpent, with his cunning, seduced Eve, and I am afraid that in the same way your ideas may get corrupted and turned away from simple devotion to Christ. Because any new-comer has only to proclaim a new Jesus, different from the one that we preached, or you have only to receive a new spirit, different from the one you have already received, or a new gospel, different from the one you have already accepted – and you welcome it with open arms. As far as I can tell, these arch-apostles have nothing more than I have. I may not be a polished speechmaker, but as for knowledge, that is a different matter; surely we have made this plain, speaking on every subject in front of all of you.

  The Church, that is, the assembly, is designated by this apt term, because it assembles all and brings them together, as the Lord says in Leviticus: Assemble all the congregation at the door of the tent of meeting. Moreover it is worth noting that this word ‘assemble’ is first used in scripture in the place where the Lord appointed Aaron to the high priesthood. And in Deuteronomy God says to Moses: Assemble the people that they may hear my words, that they may learn to fear me. He mentions the Church or assembly again when he speaks of the tables of the law. In them were written all the words which the Lord spoke with you on the mountain, out of the midst of the fire, on the day of the Church or assembly – or to put it more clearly, On the day on which you were called by the Lord and assembled together. The psalmist also says: I will give you thanks, O Lord, in the great Church, in the gathering of the throng I will praise you.

  Earlier the psalmist had sung: Bless the Lord in the Church, bless God, you who are Israel’s sons. The second Church the Saviour built from the Gentiles, our holy Church of the Christians, of which he said to Peter: On this rock I will build my Church, and the powers of death shall not prevail against it.

  After the particular Church of Judaea was repudiated, many Churches of Christ are now multiplied throughout the whole world, of which it is written in the psalms: Sing to the Lord a new song, let his praise be in the Church of the saints. Echoing this the prophet said to the Jews: I have no pleasure in you, says the Lord of Hosts and immediately adds, For from the rising of the sun to its setting my name is great among the nations. About the same holy Catholic Church Paul writes to Timothy: That you may know how one ought to live in the household of God, which is the Church of the living God, the pillar and bulwark of the truth.
