III; Spanish: Pedro III; born Markus Josef Odermatt; 13 March 1966), also known by the religious name Eliseo María de la Santa Faz, is the fourth Pope of the Palmarian Catholic Church, who in this capacity, claims to be the 266th Pope of the Catholic Church from 22 April 2016 to the present.

He joined the Order of Carmelites of the Holy Face in 1985 and worked for eighteen years as a missionary in South America.

[6] In 2016 he succeeded Ginés Jesús Hernández as Pope of the Palmarian Catholic Church, taking the papal name Peter III.

Some months later he published an encyclical letter, in which he accused his predecessor of discrediting his former Church and of stealing two million euros from the Palmarian Catholic Church, alongside several goods (including a BMW X6): he subsequently declared him an apostate, excommunicated him and declared all of his acts to be null and void.

[9] During his office, the Palmarian Catholic Church established an online presence for the first time, opening a website and accounts on Facebook, Instagram, Twitter, Pinterest and a channel on YouTube.
