"made him think of the Resurrection. He little thought that the Magdalen might be at his side"

The Resurrection
Public DomainThe Resurrection - Credit: Fra Angelico
In the Gospels of Matthew and John, the resurrection of Jesus Christ is first discovered by Mary Magdalen when she comes to his tomb in the burial garden and finds the body gone. It is early morning and because of the poor light she doesn't at first recognise the man standing nearby, mistaking him for a gardener.

Mary Magdalen was a prostitute and social outcast, so Tess has a bit more in common with her than Angel realises.
