In Lay People in the Church we continually came upon the idea that the essential point of God's plan and the place of the faithful living stones, for God's whole purpose is to make the human race, created in his image, a living, spiritual temple in which he not only dwells but to which he communicates himself and intern receives from it the worship of a wholly filial obedience. The story therefore is, up to a point, coextensive with that of humanity itself, we may even say with that of the world. So Holy Scripture not only speaks to us of God's presence in all things, it also shows us God bestowing his Presence on the first fathers of the race i a manner that we may almost call familiar. However, it is not this particular chapter in the history of the divine Presence that we propose to write, but rather those which begin with the positive, collective economy of salvation when Abraham was called, Genesis 12. We hope that we shall not disappoint the expectations of soul such as these. Yet the circumstances and the manner in which this study has been written - its first outline goes back to lectures given during the Cours Saint-Jacques in 1947 - have obliged us to be somewhat technical in our approach. Not that we can claim that we are capable of writing a study of the Scriptures by utilizing all the scientific resources of exegesis.

Not that we can claim that we are capable of writing a study of the Scriptures by utilizing all the scientific resources of exegesis. Far from it. However, we have attempted to use a method that is valid from the point of view of exegesis and so historically accurate.
