Theophylact of Ohrid
Catena Aurea · Lukasevangelium 14
And there went great multitudes with him: and he turned, and said unto them, If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. And whosoever doth not bear his cross, and come after me, cannot be my disciple.
For because many of those that accompanied Him followed not with their whole heart, but lukewarmly, He shews what kind of a man his disciple ought to be.
