For Christians, the Creator, the First cause, created everything at a point in time, the Creator himself being of course causeless and timeless.
As a boy I used to ask myself: so what of the eternal time prior to that event? However long creation lasts, even if forever, it cannot be longer than all the time in the past without creation. Both ‘the void’ and creation would be infinite (one-way) in time. As far as duration goes, the work of this God would not surpass the state of non-existence (prior to the act of creation).
And having spent eternity in inactivity, what was it that all at once gave him the urge to create? So that we here, on the one planet in the universe that harbours life (!), 4,000 years after creation, would be saved by his only son! Really?
One of the many charges of heresy levelled against Giordano Bruno by the ‘Holy’ Inquisition was, besides his belief in the ‘transmigration of souls’, even to animals, was his affirmation of the ‘plurality of worlds’ and of an infinite number of inhabited planets in an infinite universe. The trouble with that, as far as the Roman Church was concerned, was that Christ would have to eternally ‘go doing the rounds’, as it were, being crucified time after time, saving one humanity after another endlessly! Bruno was burned at the stake in the year 1600, a martyr to free thought and defiance of dogmatic ecclesiastical authority. He dabbled in occult, mysterious literature – and I wonder where exactly he got his ideas from.
