黑格爾宗教哲學的「思辯進路」，展現「內在的聖三一」中，神性理念的內容。神性理念通過自身外在化，映現為自然事物，通過人類意識的返照，在純粹思想的以太中，展現神性理念的演化，引領人回復上帝，因此完成一個自成起結的圓圈，具體表現在《哲學全書》；宗教哲學的「經驗進路」，以自然界經驗為起點，通過揚棄自然事物、主觀認知的有限性，逐步提昇到純粹總念。進而以「神性總念」為起點，通過自身分化，映現為自然事物和人類意識，也可以形成圓圈。「內在的聖三一」係屬於思辯秩序，「外在的聖三一」係屬於經驗秩序，從「對反的一致」觀點看，兩個秩序交互映現，這正是「思辯」一詞的本義。如果將思辯秩序比擬為陰文，經驗秩序比擬為陽文，則自在地說，兩者之間是「鏡映」關係，差別僅在於彰顯的清晰度罷了。

‘Speculative Approach’ of Hegel’s philosophy of religion explicates how divine idea unlock itself to pass over into nature, and via the reflection of finite spirit, leading human consciousness back to knowledge of divine idea. The image of reflection suggests that the spiritual elevation of finite spirit to God be at the same time the self-restoration of absolute spirit. ‘Empirical Approach’ of Philosophy of Religion explicates how human beings undergo the various stages of shapes of consciousness by recollecting and gathering themselves up out of finitude, and attain to knowledge of God as divine Begriff. Both Approaches complement each other, and they together constitute the totality of divine life of God.
