I can, however, claim that I have done my best to verify all the statements I have made, and have appended a full bibliography for those who care to make, further researches. One thing more: Whoever writes the life of a Pope is bound to tread upon delicate ground, and to run the risk of wounding the susceptibilities of some. I would, therefore, if I have anywhere expressed opinions which are offensive to any body of Christians, express my regret here once for all, merely saying that I have at least made an honest endeavour to present controversial matter in an impartial light.
