Mark 8:15 - Coke's Commentary on the Holy Bible

And of the leaven of Herod.— See the note on Matthew 22:16. It seems evident from this passage, that the Herodians were of the sect of the Sadducees; for what St. Mark calls the leaven of Herod, St. Matthew, in the parallel passage, calls the leaven of the Sadducees. Herodian, therefore, was but another name for such sort of Sadducees as maintained the expediency of submitting to the innovations introduced by Herod and the Romans; for it may easily be thought, that those who favoured Herod and the powers who supported him, were generally of this sect. At the same time all the Sadducees were not Herodians, some of them shewing little of that complaisance to the reigning powers, for which their brethren were so remarkable: and this accounts sufficientlyfor the distinction between the Herodians and Sadducees, found Matthew 22:16; Matthew 22:46.
