Christianity; the World's Most Violently Persecuted Religion

[Mister Agenda]

There is the paradox of free will of course, or theological fatalism, but this might also apply to any deity itself, if it was omniscient it must necessarily know the future exactly as it will happen, or put a limit on it's knowledge. If it knew the future exactly as it would happen, then it could not change it, hence it would have no autonomy, let alone be omnipotent. 

Aquinas has suggested that to ascribe the ability to do the impossible to omnipotence is an error in conception, that while we can imagine the impossible, loosely speaking, we cannot actually dot the i's and cross the t's when it came to actually fitting it within reality.  It raises the question of whether or not an omniscient being can make a triangle that has four sides?  Now one certainly can answer this in two ways, but it doesn't immediately seem unreasonable to suggest that the very concept of a triangle is that it does not have four sides, and that suggesting that it could have four sides is to abuse reason and the very concept itself.  Do you disagree?

My impression is that most theologians are fine with limiting God to the possible, while most other believers in God are not. After all, why should God be limited by logic when he is the reason logic works?
