- The common objection to the idea of the unity of religion.
- Analogy of cultural life: the evolution and incredible diversity of human expression in no way invalidates the fact that humanity constitutes one "human race".
- A similar process characterizes religious life. Differing teachings, designed to meet the needs of each age, proceed from one source, forming one religion.
- Eternal versus transitory teachings: Religion's core message is immutable; auxiliary guidance is designed to enhance the process of civilization building.
- Importance of the recognition of God's revelation at its appearance. Failure to do so condemns people to practices that have long fulfilled their purpose.
- Typically, theology has assumed it had the right to interpret God’s purpose.
- Theology constructed its own authority in the heart of each great faith.
- Result: the construction of barriers between faiths. Each stage in a progressively unfolding revelation became frozen in time.
