"I am thou..." is a common quote of the signature Personas of the protagonists of the Persona series when they are being summoned the first time. The complete quote varies a bit throughout the series, but the general meaning is almost the same. Archaic grammar is deliberately used here to denote the figure that the Persona is based on originated from ancient mythology.
Similar words may be spoken by Philemon depending on the actions the player takes at the end of Persona 2: Innocent Sin, referring to the fact that Philemon, as one personification of the Collective Unconscious, lives within the protagonists just as their Personas do.
