339. In the three foregoing chapters it has been sufficiently shown that by the "man and his wife" is signified the Most Ancient Church, so that it cannot be doubted, and this being admitted, it is evident that the conception and the birth effected by that church were of the nature we have indicated. It was customary with the most ancient people to give names, and by names to signify things, and thus frame a genealogy. For the things of the church are related to each other in this way, one being conceived and born of another, as in generation. Hence it is common in the Word to call things of the church "conceptions" "births" "offspring" "infants" "little ones" "sons" "daughters" "young men" and so on. The prophetical parts of the Word abound in such expressions.
