“Is this Christianity at all?”
Doctrines the faith cannot lose and still be the faith: that Christ is fully God and fully man, that he bodily rose from the dead, that God is Trinity, that sinners are justified by faith alone, that Scripture speaks with God's own authority. These are the truths the ancient creeds were built to guard. To deny one is not to join a different denomination — it is to stand outside Christianity while perhaps still borrowing its words, the first move of every group the church has had to call a cult. These are the doctrines a follower of Christ must hold, the ones worth dying for.
- Deity & humanity of Christ
- Bodily resurrection
- The Trinity
- Justification by faith alone
- Substitutionary atonement
- Authority of Scripture
The line it draws: between Christian and non-Christian.
For I delivered unto you first of all that which I also received… 1 Corinthians 15:3
Paul's first of all — ἐν πρώτοις, “among the first things” — is the oldest triage decision on record.
