"We should be apostles of good with at least the same zeal and interest with which the wicked propagate evil. For every effort, for every sacrifice, which we make for the Children of Christ as yet outside the Church of Christ, we shall receive a hundred-fold return."

"Knowing the author personally and admiring his qualities of mind and heart; his sound learning, his rare powers of exposition as a teacher, his priestly zeal and earnestness, I feel confident that his book will be helpful to many souls in this country."
