creed

Oh! who young Leila's glance could read / And keep that portion of his creed / Which saith, that woman is but dust, / A soulless toy for tyrant's lust?

A creed is a manifesto of religious or spiritual beliefs

Oh love! how perfect is thy mystic art, / Strengthening the weak, and trampling on the strong, / How self-deceitful is the sagest part / Of mortals whom thy lure hath led along— / The precipice she stood on was immense, / So was her creed in her own innocence.
