Tomislav Vlašić

Tomislav Vlašić (16 January 1942 – 20 October 2025) was the founder and leader of the Church of Jesus Christ of the Whole Universe seated in Italy. He was best known for being a former spiritual director of the alleged seers of the Marian apparitions in Medjugorje. He also claimed to receive the messages from God the Father, the Holy Spirit, the Blessed Virgin Mary, the Apostles, and the archangels.

He was a former Franciscan friar and Catholic priest, an adherent of the Catholic Charismatic Renewal. He became the spiritual director of the alleged seers of the Marian apparitions in Medjugorje in October 1981. Vlašić was the author of the chronicles of apparitions, a chronology that follows the alleged apparitions. In August 1984, Vlašić was replaced by Franciscan friar Slavko Barbarić. He remained actively involved in the Medjugorje phenomenon at least until 1991. He was one of the founders of the Medjugorje International Youth Festival (Mladifest), an annual gathering of the Catholic youth, established to mark Our Lady's birthday as claimed by the seers.

In 1987, he moved to Italy and founded the community "Queen of Peace – Totally Yours – to Jesus through Mary" with the alleged approval from Madonna, as proclaimed by Marija Pavlović, one of the alleged seers. Pavlović subsequently disavowed the organisation. In 2009 Vlašić was laicized after accusations of sexual misconduct, and was excommunicated in 2020.

In 2018, with a group of followers, Vlašić established the Church of Jesus Christ of the Whole Universe, led by himself and his associate Stefania Caterina in Ghedi near Brescia in Italy.
