'What is the similarity between the Cause of Christ and that of Baha'u'llah? and what relation do they hold toward each other?':
' The foundation of the religion of God is one. The same basis which was laid by Christ and later on was forgotten, has been renewed by His Holiness Baha'u'llah. Each divine revelation is divided into two parts. The first part is essential and belongs to the eternal world. It is the exposition of significances and realities. It is the expression of the love of God, the knowledge of God. This is one in all the religions, unchangeable and immutable. The second part is not eternal; it deals with practical life, transactions and business and changes according to the evolution of man and the requirements of the time of each prophet..
