Origen
Catena Aurea · Matthäusevangelium 23
Then spake Jesus to the multitude, and to his disciples, Saying, The Scribes and the Pharisees sit in Moses’ seat: All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not. For they bind heavy burdens and grievous to be borne, and lay them on men’s shoulders; but they themselves will not move them with one of their fingers.
The disciples of Christ are better than the common herd; and you may find in the Church such as with more ardent affection come to the word of God; these are Christ’s disciples, the rest are only His people. And sometimes He speaks to His disciples alone, sometimes to the multitudes and His disciples together, as here. The Scribes and Pharisees sit in Moses’ seat, as professing his Law, and boasting that they can interpret it. Those that do not depart from the letter of the Law are the Scribes; those who make high professions, and separate themselves from the vulgar as better than they, are called Pharisees, which signifies ‘separate.’ Those who understand and expound Moses according to his spiritual meaning, these sit indeed on Moses’ seat, but are neither Scribes nor Pharisees, but better than either, Christ’s beloved disciples. Since His coming these have sat upon the seat of the Church, which is the seat of Christ.
