"We, therefore, both know and confess that God is without beginning, without end, eternal and everlasting, uncreate, unchangeable, invariable, simple, uncompound, incorporeal, invisible, impalpable, uncircumscribed, infinite, incognisable, indefinable, incomprehensible, good, just, maker of all things created, almighty, all-ruling, all-surveying, of all overseer, sovereign, judge; and that God is One...."
-- St. John Damascene, "An Exact Exposition of the Orthodox Faith", Book One, Chapter Two.
I have heard that on one occasion the Blessed One [i.e., the Buddha] was staying near Savatthi, in Jeta's Grove, Anathapindika's monastery. Now at that time the Blessed One was instructing urging, rousing, and encouraging the monks with Dhamma-talk concerned with Nibbana. The monks — receptive, attentive, focusing their entire awareness, lending ear — listened to the Dhamma.
Then, on realizing the significance of that, the Blessed One on that occasion exclaimed:
"There is, monks, an unborn — unbecome — unmade — unfabricated. If there were not that unborn — unbecome — unmade — unfabricated, there would not be the case that emancipation from the born — become — made — fabricated would be discerned. But precisely because there is an unborn — unbecome — unmade — unfabricated, emancipation from the born — become — made — fabricated is discerned."-- Nibbana Sutta
