Reply to Objection 4: Those things which pertained to the mode of life of the people who worshipped God, retained the common designation of observances, in so far as they fell short of the above. For they were not called sacred things, because they had no immediate connection with the worship of God, such as the tabernacle and its vessels had. But by a sort of consequence they were matters of ceremony, in so far as they affected the fitness of the people who worshipped God.
Reply to Objection 5: Just as the sacrifices were offered in a fixed place, so were they offered at fixed times: for which reason the solemn festivals seem to be reckoned among the sacred things. The oblations and gifts are counted together with the sacrifices; hence the Apostle says ( Heb. 5:1 ): "Every high-priest taken from among men, is ordained for men in things that appertain to God, that he may offer up gifts and sacrifices."
