This is Religion! to Dear Catholic World: Why do YOU Remain a Catholic?

One reason, because, ‘This is Religion’.

[In] the catholic Church … I recognized at once a reality which was quite a new thing with me. Then I was sensible that I was not making myself a Church by an effort of thought; I needed not to make an act of faith in her; I had not painfully to force myself into a position, but my mind fell back upon itself in relaxation and in peace, and I gazed at her almost passively as a great objective fact. I looked at her; at her rites, her ceremonial, and her precepts; and I said, ‘This is a religion’.
