Episode notes
Consulting The Faithful As Evidence
- John Henry Newman distinguishes two senses of 'consult': submitting to judgment and inquiring into a state of affairs.
- The sensus fidelium is an evidential sign the Church must consult before defining doctrine, not a popular vote to decide it.
Historical Examples Of Lay Fidelity
- Pius IX consulted bishops and took a kind of poll of the faithful before defining the Immaculate Conception in 1854.
- Newman points to the fourth-century Arian controversy where lay fidelity sometimes outshone bishops as an illustration.
Conscience Grounds Authority
- Newman starts from conscience to argue the reasonableness of revelation and a church vested with supreme authority.
- He concludes that an infallible authority is necessary to transmit revelation and heal humanity's alienation from God.
