Love is the beginning, the middle, and the end of everything.

There is nothing fruitful except sacrifice.

There exists an infinite, eternal Being, subsisting of himself, who is one without being alone; for he finds in his own essence relations whence, with the necessary movement of his life, results the absolute plenitude of his perfection and his happiness.
