Jesus's two options — "from heaven or from men" — establish a "sola heaven" principle: heavenly authority doesn't need earthly institutional approval. John didn't get Sanhedrin permission; neither does Jesus.

If John's baptism is FROM HEAVEN: (1) John was honestly pointing to Jesus, validating Jesus's identity; (2) The Sanhedrin's gatekeeping role is unnecessary — John operated entirely outside their institutional approval. This implies a "sola heaven" principle where God's authority doesn't need human institutional endorsement. If FROM MEN: Jesus subtly puts the Sanhedrin in the "men" category — "you teach the traditions of men as though they are the commands of God" (Mark 7:8-9). Key distinction: the Sanhedrin has RESPONSIBILITY (to teach God's truth faithfully) but not AUTHORITY (to determine what is true). Teachers echo truth; they don't create it.
