It is to be expected, then, that men should have agreed upon certain conventional actions as expressing adoration of the Supreme Being.Of these actions, one has pre-eminently and exclusivly signified adoration, and that is sacrifice.Moreover, it would do religious grievous harm to check its tendency to outward manifestation, since the external expression reacts upon the interior sentiment, quickening, strengthening, and sustaining it.
Concerning the verbal manifestation of adoration -- that is, the prayer of praise - explanation is not necessary.
This was clearly an act of adoration in its highest sense; yet that it could have other meaning, we know from, e.g., 1 Samuel , which says that David adored "falling on his face to the ground" before Jonathan, who had come to warn him of Saul's hatred.
In like manner Gen xxxi;; 3 narrates tbat Jacob, on meeting his brother Esau "bowed down with he face to the ground seven times".
In the strict sense, an act of religion offered to God in acknowledgment of His supreme perfection and dominion, and of the creature's dependence upon Him; in a looser sense, the reverence shown to any person or object possessing, inherently or by association, a sacred character or a high degree of moral excellence.
The rational creature, looking up to God, whom reason and revelation show to be infinitely perfect, cannot in right and justice maintain an attitude of indifference.
