What you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith; yet faith does not desire instruction
Saint AugustineWhat art Thou then, my God? what, but the Lord God? For who is Lord but the Lord? or who is God save our God? Most highest, most good, most potent, most omnipotent; most merciful, yet most just; most hidden, yet most present; most beautiful, yet most strong; stable, yet incomprehensible; unchangeable, yet all-changing; never new, never old; all-renewing, and bringing age upon the proud, and they know it not; ever working, ever at rest; still gathering, yet nothing lacking; supporting, filling, and overspreading; creating, nourishing, and maturing; seeking, yet having all things.
Saint AugustineWhat then, is correctness of speech but the maintenance of the practice of others, as established by the authority of ancient speakers? But the weaker men are, the more they are troubled by such matters. Their weakness stems from a desire to appear learned, not with a knowledge of things, by which we are edified, but with a knowledge of signs, by which it is difficult not to be puffed up in some way; even a knowledge of things often makes people boastful, unless their necks are held down by the Lord's yoke.
Saint AugustineThou hast created us for Thyself, and our heart is not quiet until it rests in Thee.
Saint Augustine
