The Holy Scripture
Epistle of Barnabas
Chapter XIX
This then is the way of light, if anyone desiring to travel on the way to his appointed place would be zealous in his works. The knowledge then which is given to us whereby we may walk therein is as follows.
Ἡ οὖν ὁδὸς τοῦ φωτός ἐστιν αὕτη: ἐάν τις θέλων ὁδὸν ὁδεύειν ἐπὶ τὸν ὡρισμένον τόπον, σπεύσῃ τοῖς ἔργοις αὐτοῦ. ἔστιν οὖν ἡ δοθεῖσα ἡμῖν γνῶσις τοῦ περιπατεῖν ἐν αὐτῇ τοιαύτη.
