" Anyone who investigates the revealed religions with an open mind and a discerning heart is bound to discover the truth in all of them. Of course, there are notable differences between them. Each faith is distinguished by the personality of its messenger and the circumstances of its revelation. With the passing of time, faith traditions are also subject to the proliferation of distorted interpretations. Nonetheless, to seeing eyes it is plain to see that all of the world‘s great faiths harbor at their core the same message of love […] Through whichever channel Providence pours it out to the thirsty, the divine love that flows through revelation is from first to last a single substance. All fields are watered with one water. (p. 255) "
