Well nobody's perfect :) But I think his point is valid. Basically, he's echoing Kant's ideas on Enlightenment. A person can believe whatever faith he chooses to, but to be enlightened, he can't believe blindly. He has the responsibility to challenge dogma that he feels conflicts with the true meaning of his faith. He also shouldn't ignore or reject the physical world, but seek to understand it as well, and educate himself on physics, mathematics, etc. The reverse is also true. A scientist shouldn't dismiss any religious belief as "ignorance". He should seek to understand them and challenge dogma to "improve" the religion, not destroy it. IE, he would challenge the Church's stance on homosexuality on the grounds that Jesus would have accepted homosexuals as he did prostitutes and tax collectors. Einstein saw both expanding our understanding of the physical word and improving belief systems as actions with the same goal. Both actions would benefit and improve humanity, physically and spiritually. From Einstein's point of view, a religious person who says science is the work of the Devil, and a scientist who broadly labels all religious people as stupid morons would both be "ignorant".
