Gospel of Christ preaching in Nazareth, from a sermon by St. Simeon the New Theologian:
Many people never stop saying – I have heard them myself – “If only we had lived in the days of the apostles, and been counted worthy to gaze upon Christ as they did, we should have become holy like them.” Such people do not realise that the Christ who spoke then and the Christ who speaks now throughout the whole world is one and the same. If he were not the same then and now, God in every respect, in his operations as in the sacraments, how would it be seen that the Father is always in the Son and the Son in the Father, according to the words Christ spoke through the Spirit: My Father is still working and so am I?
But no doubt someone will say that merely to hear his words now and to be taught about him and his kingdom is not the same thing as to have seen him then in the body. And I answer that indeed the position now is not the same as it was then, but our situation now, in the present day, is very much better. It leads us more easily to a deeper faith and conviction than seeing and hearing him in the flesh would have done.
