"Of course, the word ‘religious’ implies some ideas and beliefs that are fundamental. Among these we may reckon the belief in the immortality of the soul, its future existence in eternity, the belief in the existence of a Higher Being, and so on. But all these ideas, no matter how firmly the individual believes in them, may be critically analysed by any person and accepted or rejected accordingly, until the emotional concept or yearning has been transformed into an active service that is governed by a clearly defined doctrinal faith. Such a faith furnishes the practical outlet for religious feeling to express itself and thus opens the way through which it can be put into practice."
