Amid all these details let us take care not to lose the one great lesson of the passage. Christian people owe a testimony to Christ. His name has been pronounced over them, and all who look at them ought to see His nature. We should discern in the heart and in the behaviour of Christians the handwriting, let us say the characters, not of avarice, of suspicion, of envy, of lust, of falsehood, of pride, but of Christ. It is to us He has committed Himself; we are the certification to men of what He does for man; His character is in our care. The true epistles of Christ to the world are not those which are expounded in pulpits; they are not even the gospels in which Christ Himself lives and moves before us; they are living men and women, on the tables of whose hearts the Spirit of the living God, ministered by a true evangelist, has engraved the likeness of Christ Himself. It is not the written Word on which Christianity ultimately depends; it is not the sacraments, nor so-called necessary institutions: it is this inward, spiritual, Divine writing which is the guarantee of all else.
[23] The true reading of the last words in ver. 3 is doubtful. The Received Text has ἐν πλαξὶ καρδίας σαρκίναις. This is as old as Irenæus and Origen, and is found in many versions. Almost all MSS. give the reading which is translated in the Revised Version: ἐν πλαξὶ καρδίαις σαρκίναις(א, A, B, C, D, etc.); and this is adopted by most of the purely critical editors. Some, however, and many exegetes, suspect a primitive error, affecting all MSS. and versions. Schmiedel would omit καρδίαις or καρδίας, as a marginal note, suggested by Prov. vii. 3, Jer. xvii. 1; Westcott and Hort, on the other hand, think that πλαξὶ may be a primitive interpolation. No certainty is possible; but considering Old Testament usage, one would expect Paul to write ἐν πλαξὶ καρδίας almost unconsciously.
