"The Hindu, sickened by idolatry (Islam's and Christianity's common name for Hinduism), turns to the other two religions which surround him, and inquires into their respective claims ... we must be ready at hand to meet him with the proofs of our most holy faith... the comparison of the two religIOns, Christianity and Islam, cannot fail to be of essential service, under God's blessings, to lead to practical results."
