70 I am alarmed by the reproaches of the Pharisees, the conviction of the Scribes. For it is disgraceful for us, who ought greatly surpass them, as we are bidden, if we desire the kingdom of heaven, to be found more deeply sunk in vice: so that we deserve to be called serpents, a generation of vipers, and blind guides, who strain out a gnat and swallow a camel, or sepulchres foul within, in spite of our external comeliness, or platters outwardly clean, and everything else, which they are, or which is laid to their charge.
