I am not engaged to Christianity by decent forms, or saving ordinances; it is not usage, it is not what I do not understand, that binds me to it -- let these be the sandy foundations of falsehoods. What I revere and obey in it is its reality, its boundless charity, its deep interior life, the rest it gives to my mind, the echo it returns to my thoughts, the perfect accord it makes with my reason through all its representation of God and His Providence; and the persuasion and courage that come out thence to lead me upward and onward.
