Not "here is what Christianity is" — the encyclopedias own that. Here is how three very different traditions answer the same human questions, and where they part ways. Stoicism sits in as the philosophical yardstick they all get measured against.
Theistic · the Western reference point
Suffering enters a good world and is answered by a God who suffers too. Meaning runs through fall, grace, and redemption — the claim that the divine stepped into the wound rather than explaining it away.
→ Suffering as redemptive; the soul; a personal God who acts in history.

Non-theistic · the great Eastern challenge
No creator to defend, and no fixed self to save. Suffering comes from clinging; the way out is to loosen the grip. A religion that answers the big questions by dissolving one of them.
→ Dukkha and detachment; no-self (anatta); Nirvana instead of God.
Step inside →
Naturalistic · the way of the Tao
Stop fighting the current. The Tao can't be named or argued into a system; you align with it by doing less, forcing nothing — wu wei. Meaning as harmony, not doctrine.
→ The Tao vs. a personal God; wu wei; the self as part of nature.
Step inside →
The yardstick · philosophy, not religion
Stoicism
The reference point every comparison keeps returning to: control what you can, accept what you can't, and let reason govern the rest. Placed here because the sharpest questions are "Buddhism vs. Stoicism," "Taoism vs. Stoicism."
→ Reason and acceptance; virtue as the only good; the examined life.
