There are therefore two things that contribute to a person’s attaining beatitude: correct views on doctrine, for the purpose of having a dutiful and upright attitude toward God, and a disciplined moral upbringing, for living in an honorable and sound manner. Neither suffices for perfection without the other, each being supplemented or accompanied by the other; faith takes pride of place among them, just as in the body the head is given greater esteem than the other members. Still, for a person’s perfection, relationship with the other members and conjunction of the limbs also are required; likewise, for the full development of life, both these things must come together–namely, faith and life.

-Theodore of Mopsuestia
