De León's incorrupt body is still preserved in the Monastery of St. Catherine, where she lived out her life and died.
Every 15 February (the anniversary of her death), her body is placed on public display in a glass-covered coffin, which was donated by the corsair Amaro Pargo, who was present at the exhumation.
Because of the large numbers of pilgrims and devotees who desire to see her incorrupt body, the coffin is also displayed on the following Sunday.

A formal inquiry into De León's life for possible canonization was begun in the 19th century, but soon ceased.
The cause was reopened in 1992 and has been submitted to the Vatican.
It remains pending.
Supporters of her cause are dismayed by this lack of progress, despite a document from 1771 which lists 1,251 miracles attributed to her intercession.

Although she has not yet been officially canonized, veneration of Sister Mary of Jesus has become the equivalent in the Canary Islands in cults of Saint Teresa of Jesus in the rest of Spain, Saint Catherine of Siena in Italy and Saint Rose of Lima in Peru and Latin America.
