John 8:12

πάλιν οὖν. The paragraph John 7:53 to John 8:11 being omitted, these words must be connected with John 7:52. The officers have made their report to the Sanhedrin, leaving Jesus unmolested. After an interval He continues His discourse: again, therefore, Jesus spake unto them, i.e. because the attempt to interfere with Him had failed. How long the interval was we do not know, but probably a few hours.

ἐγώ εἰμι τ. φῶς τ. κ. see on John 6:35. Once more we have a possible reference to the ceremonies of the Feast of Tabernacles, somewhat less probable than the other (see on John 7:37), but not improbable. Large candelabra were lighted in the Court of the Women on the evening of the first day of the Feast in memory of the pillar of fire at the Exodus, and these flung their light over the whole city. Authorities differ as to whether this illumination was repeated, but all are agreed that it did not take place on the last evening. Here, therefore, there was once more a gap, which Christ Himself may have designed to fill; and while the multitude were missing the festal light of the great lamps, He declares, ‘I am the Light of the world.’ ‘Light,’ according to tradition, was one of the names of the Messiah. In the case of the water we know that it was poured on each of the seven days, and that Christ spoke the probable reference to it on the last day of the Feast. But in this case the illumination took place possibly on the first night only, and Christ certainly did not utter this possible reference to it until the last day of the Feast, or perhaps not until the Feast was all over. But the fact that the words were spoken in the Court of the Women (see on John 8:20) makes the reference not improbable; and πάλιν may point to this: Jesus having appropriated the type of the Rock, now appropriates that of the Pillar of Fire.

ὁ�. This expression also is in favour of the reference. ‘The Lord went before them by day in a pillar of a cloud to lead them the way; and by night in a pillar of fire, to give them light’ (Exodus 13:21). So Christ here declares that those who follow Him shall in nowise walk in the darkness. The negative (οὐ μή) is very strong. This use of ‘darkness’ for moral evil is peculiar to S. John: see on John 1:5, where (as here) we have light and life (John 8:4) closely connected, while darkness is opposed to both.

ἕξει. Not only with him but in him, so that he also becomes a source of light. see on John 7:38 and comp. ‘Ye are the light of the world’ Matthew 5:14. Τῆς ζωῆς means ‘giving life’ not merely ‘leading to life:’ see on John 6:35 and John 1:4. Note that as in the case of the living bread and the living water so also here the believer is not a mere passive recipient; he has to eat and to drink to appropriate the heavenly food, and here he has to follow to appropriate the heavenly light. In the early Church candidates for baptism first turned to the West and renounced Satan and his works and then to the East, ‘the place of light,’ and professed allegiance to Christ (the Light of the world and the Sun of righteousness) and a belief in the Trinity (Dionys. Areop. Eccl. Hier.; S. Cyril Cat. Myst. I.) From this very ancient custom the practice of turning to the east at the Creed is derived. Comp. Tert. Apol. XVI.; In Valent. III.; Apost. Const.
