The Powerful Hand is a large hand bearing stigmata with blood issuing forth into a chalice. In some retablos, the chalice sits on a book with seven seals, a reference to the Book of Revelation. The blood then spills from the chalice into the mouths of seven sacrificial lambs, representing the seven sacraments. This is the blood of Christ, which in Christian tradition washes away the sins of the world. At the tip of each finger is a figure, seated within a cloud or a lily. The five figures, also called the Five Persons, are Mary, Joseph, Jesus, and Mary's parents, Anne and Joachim. The crown of thorns and the tools of the crucifixion are commonly seen in the foreground.
