Nicholas of Cusa was a cardinal of the Catholic Church who lived during the 1400's. He was a great philosopher, mathematician and scientist.

He applied mathematical symbols and concepts to theology. To him, God was the ultimate union between opposites. His most famous observation was this:

Given a circle with a radius "R", a central angle "A", and an arc length "L", the equation for A will, obviously, be

A = (360*L)/(2piR).

If the arc length (L) stays constant, as the radius (R) approaches infinity, the angle A will approach zero. The arc length will, therefore, become a line when the radius is inifinitely large. Every line might simply be part of an infinitely large circle (for, example, the line of time). . .

Because such a union of opposite - the line and the arc - coincide in inifinity, God is, therefore, inifnity. He also made some additional observations about how opposite extremes met in inifinity as well.
