Pedro Marieluz Garcés (or Peter Marielux) (1780 – 23 September 1825)[1] was a Roman Catholic priest who died as a martyr of the Seal of the Confessional.
Later he became a military chaplain with the troops of the Spanish Royal Governor, Ramón Rodil.
During the siege of the fortress Real Felipe in the city of Callao after the Battle of Ayacucho, there was a conspiracy made against Rodil by some of the Royal soldiers.
After the execution of the plotters, Rodil is said to have doubted whether he had convicted all members of the plot and, thinking that the executed ones would have revealed everything in confession to Marieluz, he tried to force the confessor to disclose to him what he had heard in the confessions by threatening him to be shot likewise, if he would not obey.
But Marieluz remained steadfast and was executed on the evening of 23 September 1825, becoming a martyr in the eyes of the Catholic Church.
