Are you being serious Gonners!?! 
I cannot speak about Islam, but the suggestion that christian societies promoted education for all over many centuries is absolutely laughable.
Up until the mid Victorian era (arguably continuing today amongst evangelicals) christian societies did not promote education for all but only for the very elite and indeed 'education' was mostly just religious instruction. Actually Christian societies went further than being against widespread education with a broad curriculum for all - they were inherently anti-intellectual. Good examples being Galileo and Darwin - those that used science to discover truths about the word were ostracised by the christian establishment if those facts had the temerity to challenge unevidenced christian dogma.
So for centuries christian societies kept the vast majority poor, uneducated and without power - which is exactly how the elites (who of course included the religious elite) wanted it.
Just a footnote on Galileo, because anti-Christians do see him as some sort of martyr to the truth. I don't exactly approve of the Catholic Church's treatment of him, but he was in some respects his own worst enemy. He had published his "Dialogue of the two world systems" in which he gave the arguments for the geocentric theory to a character called
Simplicio, who is clearly a caricature of the contemporary Pope Urban, and uses words that the pope himself had used in argument. The pope was very much a "right man", as was Galileo himself, and the pope was not best pleased. The Inquisition asked for
proof of Galileo's heliocentric hypothesis, and it is a fact that at that time Galileo did not have ultimate proof**, though all his arguments made good scientific sense. He was originally told that he could publish, if only he would state that this was not ultimate scientific fact, I believe. Instead, he met the pope head on, like a bull at a gate.
He was lucky not to be tortured - instead he got away with relatively comfortable house arrest, and the Catholic Church clamped down hard on the heliocentric theory for centuries to come. Clash of personalities can be as much an enemy to the progress of science as anti-scientific ignorance.

"It was Isaac Newton that finally derived the mathematical proof for the heliocentric solar system, by using Kepler's laws. Kepler, by this time, had determined the planets were in elliptical orbits. The next major development was the generalization of Kepler's laws in 1687 by Isaac Newton (1642-1727)."
