Letter of an Inquirer
1 Beloved, I send you inquiries and questions, for I am compelled to seek further instruction of you on many points. Do not refuse to hear me. My spirit urges me to warn you about many topics that you may unfold for me the spiritual perceptions of your mind, and may show me of all that you have apprehended from the holy books, that so my deficiency may be supplied by you and my hunger satisfied by your doctrine, and that you may assuage my thirst from the fountain of your instruction. Yet though many things are set in my thought to ask you, they all are notwithstanding reserved with me, that when I come to you, you may instruct me on all subjects.
2. But before all things I desire that you would write and instruct me concerning this that straitens me, namely, concerning our faith; how it is, and what its foundation is, and on what structure it rises, on what it rests, and in what way is its fulfilment and consummation, and what are the works required for it. For I of myself firmly believe that God is one, Who made the heavens and the earth from the beginning; that He adorned the world by His handiwork; that He made man in His image; He it is that accepted the offering of Abel. He translated Enoch because of his excellence. He preserved Noah because of his righteousness. He chose Abraham because of his faith. He spoke with Moses on account of his meekness. He it is that spoke in all the prophets, and furthermore He sent His Christ into the world. Since then, my brother, I thus believe in these things that so they are, I therefore, brother, request of you that you would write and show me what are the works required for this our faith, that so you may set me at rest.
