I lived a past life in the christian church actually - so i do have karma with some aspects of the destruction that religion has brought, yes.
God is always ready to communicate directly with those who will hear - however, it is often the case that religious teachings have clouded the mind of those who want and need to hear and so they do not hear.
You are right sir, religious leaders sometimes hide treatises from god and convey their thoughts. That is why religion seems to fail to improve human morals. While some of us believe that the doctrine has been changed, and it affects the balance between man and man and between man and nature.
And do not feel guilty about what Christianity did in the early days of Europe. Is not the earth once filled with idolaters and god sent his prophet to order the worship of god.
The evils within Christianity have taken the energy of christ and made it very much anti-christ - to the point that the majority of alleged christians know very little of themselves, their light and the light of God. I do not feel guilty about it all, so much as I take action to heal it.
Yes sir, may we all be blessed and the world is always peaceful. I believe God wants the best for man, man himself who deviated from the teachings of god.
