Name these Saints

Every Saturday, I am going to run a little series called "Name these Saints." I will post one or several pictures of saints, along with a hint or two, and the readers can guess who they are. It's a great way to educate ourselves about the saints, especially if you also give a little information about the saint in the picture when you leave your guess in the combox.



In the above image, Our Lord is bestowing on this saint His own Heart in exchange for hers. She was also a stigmatist who received Communion directly from the hands of Jesus. Who is she?





Before his conversion, this saint fell victim to the Manichæan heresy. He is known as one of the great Doctors of the Church. Who is he?

Guess away!
