I have had so many evidences of [God's] direction, so many instances when I have been controlled by some other power than my own will, that I cannot doubt that this power comes from above.
There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).
Should doubt knock at your doorway, just say to those skeptical, disturbing, rebellious thoughts: "I propose to stay with my faith, with the faith of my people."
In dealing with the arrogant asserter of doubt, it is not the right method to tell him to stop doubting. It is rather the right method to tell him to go on doubting, to doubt a little more, to doubt every day newer and wilder things in the universe, until at last, by some strange enlightenment, he may begin to doubt himself.
Satisfy yourself beyond all doubt that you are qualified for the course to which you now aspire.....and try to achieve something in your own land before you venture on a strange one.
I have not a doubt of your doing very well together. Your tempers are by no means unlike. You are each of you so complying, that nothing will ever be resolved on; so easy, that every servant will cheat you; and so generous, that you will always exceed your income.
