“Then spake Jesus to the multitude, and to his disciples,”
Matthew 23:1 — Greek Interlinear
Church Fathers on Matthew 23:1
When the Lord had overthrown the Priests by His answer, and shewn their condition to be irremediable, forasmuch as clergy, when they do wickedly, cannot be amended, but laymen who have gone wrong are easily set right, He turns His discourse to His Apostles and the people. For that is an unprofitable word which silences one, without conveying improvement to another.
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.
But that none should say, For this cause am I slack to practise, because my instructor is evil, He removes every such plea, saying, 'All therefore whatsoever they say unto you, that observe and do,' for they speak not their own, but God’s, which things He taught through Moses in the Law. And look with how great honour He speaks of Moses, shewing again what harmony there is with the Old Testament.
