The Deputation from Jerusalem - the Three Sects of the Pharisees, Sadducees, and Essenes - Examination of their Distinctive Doctrines.
APART from the repulsively carnal form which it had taken, there is something absolutely sublime in the continuance and intensity of the Jewish expectation of the Messiah. It outlived not only the delay of long centuries, but the persecutions and scattering of the people; it continued under the disappointment of the Maccabees, the rule of a Herod, the administration of a corrupt and contemptible Priesthood, and, finally, the government of Rome as represented by a Pilate; nay, it grew in intensity …

Leviticus
The emphasis which modern criticism has very properly laid on the prophetic books and the prophetic element generally in the Old Testament, has had the effect of somewhat diverting popular attention from the priestly contributions to the literature and religion of Israel. From this neglect Leviticus has suffered most. Yet for many reasons it is worthy of close attention; it is the deliberate expression of the priestly mind of Israel at its best, and it thus forms a welcome foil to the unattractive …
