The Confessions And Letters Of St by St. Augustine
Chapter XXXIII.--The World Was Created by God Out of Nothing.
48. Let Thy works praise Thee, that we may love Thee; and let us love Thee, that Thy works may praise Thee, the which have beginning and end from time, -- rising and setting, growth and decay, form and privation. They have therefore their successions of morning and evening, partly hidden, partly apparent; for they were made from nothing by Thee, not of Thee, nor of any matter not Thine, or which was created before, but of concreted matter (that is, matter at the same time created by Thee), because without any interval of time Thou didst form its formlessness. For since the matter of heaven and earth is one thing, and the form of heaven and earth another, Thou hast made the matter indeed of almost nothing, but the form of the world Thou hast formed of formless matter; both, however, at the same time, so that the form should follow the matter with no interval of delay.
