Origen

He said Master tempting Him, for none but a disciple would thus address Christ. Whoever then does not learn of the Word, nor yields himself wholly up to it, yet calls it Master, he is brother to this Pharisee thus tempting Christ. Perhaps while they read the Law before the Saviour’s coming, it was a question among them which was the great commandment in it; nor would the Pharisee have asked this, if it had not been long time enquired among themselves, but never found till Jesus came and declared it.
