That's what the gnostics thought. In fact, they thought Christians were lower lifeforms for thinking that way, and not possessing the special knowledge that they were incorruptible spiritual beings. Just like you teach.
Actually that's not what they thought.
And committing many other abominations and impieties, [the gnostics] run us [Christians] down (who from the fear of God guard against sinning even in thought or word) as utterly contemptible and ignorant persons, while they highly exalt themselves, and claim to be perfect, and the elect seed.
Animal men, again, are instructed in animal things; such men, namely, as are established by their works, and by a mere faith, while [the gnostics] have not perfect knowledge. We of the Church, they say, are these persons. Wherefore also [the gnostics] maintain that good works are necessary to us, for that otherwise it is impossible we should be saved. But as to themselves, [the gnostics] hold that they shall be entirely and undoubtedly saved, not by means of conduct, but because they are spiritual by nature.
