Origen

“ And how could there be any witness-bearing about wisdom, to those who, even if they appear to know something, cannot understand pure truth, but behold it through a glass and in an enigma? It is likely, however, that before the second and diviner advent of Christ, John or Elias will come to bear witness about life a little before Christ our life is made manifest, and that then they will bear witness about the Word, and offer also their testimony about wisdom. ”

“ Why did he not come to bear witness of the life, or of the Word, or about the beginning, or about any other of the many aspects in which Christ appears? Consider here the texts, “The people which sat in darkness saw a great light,” and “The light shineth in darkness, and the darkness overtook it not,” and consider how those who are in darkness, that is, men, have need of light. For if the light of men shines in darkness, and there is no active power in darkness to attain to it, then we must partake of other aspects of Christ ”
