When we see venus in its full phase, what phase would earth be in as seen by a hypothetical venetian?

Full Next to the moon, planet Venus appears most brightly and visibly to Earth. (Because of Venus's proximity to the Sun, it gets more intense light). Venus gets closer to Earth than any other planet, presenting the same side at each closest approach at inferior conjunction. Hypothetical Venetians would see Earth as full on the other side of the Sun whenever Venus appear full also on the other side of the Sun.
