What is the school of Buddhism that believes in God?

I am a Westerner raised in the Christian faith but have left it in search of a path that fits with my beliefs and philosophy. Over the past few years, I have studied, prayed, researched, etc of the different schools of Buddhism. In my readings, a type popped up that was more of a Buddhist/Hindu mix - it was a long word that started with an "A" and that is all I can remember. Can anyone help? Thank you!
