The outward service (Θρησκεια[24]) of ancient religion, the rites,
ceremonies and ceremonial vestments of the old law, had morality for
their substance. They were the _letter_, of which morality was the
_spirit_; the enigma, of which morality was the _meaning_. But
morality itself is the service and ceremonial (cultus exterior,
θρησκεια) of the Christian religion. The scheme of grace and truth
that _became_[25] through Jesus Christ, the faith that _looks[26]
down into_ the perfect law of liberty, has _light for its garment:
its very robe is righteousness_.
