St. John Henry Newman
I have changed in many things: in this I have not. From the age of fifteen, dogma has been the fundamental principle of my religion: I know no other religion; I cannot enter into the idea of any other
I have changed in many things: in this I have not. From the age of fifteen, dogma has been the fundamental principle of my religion: I know no other religion; I cannot enter into the idea of any other sort of religion; religion, as a mere sentiment, is to me a dream and a mockery. As well can there be filial love without the fact of a father, as devotion without the fact of a Supreme Being. What I held in 1816, I held in 1833, and I hold in 1864. Please God, I shall hold it to the end.
