If you're going to go churchy on us, watch thy pronouns.
Thou: subject ("Thou said WHAT?")
Thee: object ("Yeah, I'm talkin' to thee.")
Thy: possessive ("I see by thy outfit that thou art a cowboy.")¹
¹ Update: As the Rev. Michael Penn Moore pointed out in an e-mail, that sentence should begin "I see by thine outfit..."Thy becomes thine in front of an open vowel. Aren't you glad English dropped the second person informal several centuries ago?
