Mark 16:17-18 (signs accompanying believers) — Mike thinks the last 12 verses of Mark are likely not original (earliest manuscripts lack them). Even if original: (1) the signs may apply to SOME believers, not ALL; (2) picking up serpents refers to unintentional encounters (like Paul in Acts 28), not deliberate snake handling; (3) Jesus said "do not put the Lord your God to the test"; (4) if healing applies to all, every Christian should be in hospitals — but nobody does this, revealing inconsistency.

Textual issue: ESV and most translations note the earliest manuscripts lack Mark 16:9-20. If not original, the passage is early church commentary compiled from other Gospels and Acts. Even if original: the signs may accompany some believers (not every individual). Snake handling: Paul's viper in Acts 28 was accidental, not deliberate. Jesus in Luke 4: "do not put the Lord your God to the test." Healing: if universal, Christians should be in every hospital ward — the fact nobody does this reveals the inconsistency.
