Ancient Egypt Rises Again?

The first time I read through the Second Coming, I like most everyone else thought that the poem was about the second coming of Christ. The more I read it, the more I realized that it seemed to be bashing Christianity as a whole. I may be completely out in left field here but if I am then just disregard what I'm about to say.

Yeats grandfather and great-grandfather were both prominent members in the early church of Ireland. Yeats' father was an atheist that believed that Christianity was a fable or a myth. This would give Yeats an excellent background in Christianity but at the same time leaving him room to despise it.

The best lack all conviction, while the worst
Are full of passionate intensity.

After reading this for about the seventh time I understood it to say that the best of people lack a conviction about Christianity. On the other hand though, the people that are the worst are full of zeal and intensity about it.

The Second Coming! Hardly are those words out
When a vast image out of Spiritus Mundi
Troubles my sight: a waste of desert sand;

He's still bashing Christianity talking about the second coming of Christ at this point. When the topic comes up though, something from Spiritus Mundi(Spirit of the World) seems to rise out of nowhere. This is troubling to his sight. It seems as if he finds it unattractive.

A shape with lion body and the head of a man,

Fine I'll say it, it sounds like a sphinx to me. The exact purpose of the Spinx is unknown but most people seem to associate it with the defense of the pharaoh. Who is one of the most important characters in the ancient Egyptian religion.

That twenty centuries of stony sleep

Were vexed to nightmare by a rocking cradle,

This cradle seems it scream baby Jesus to me. Not in a positive way though. Yeats seems to be blaming the cause of all the bad things that have happened on the rocking cradle.

Maybe this isn't coherent to anyone but me, but when I put this together in my head it seems like the ancient Egyptian tradition is being awakened again by Christianity. The fact that the 2000 year reign is almost over and something must take the place of it. Besides a great poem has to have some mentions of the gods in it in some way, form, or fashion doesn't it?
