In his homily, Sandri pointed to the example of St. Francis, who traveled to Egypt to meet Sultan al-Malik al-Kamil just over 800 years ago.
"The Holy Father sends you, a son of St. Francis, as the new archbishop of Tehran-Isfahan, with the hope that through your testimony, the style of presence indicated by the Seraphic Father may continue: 'speak with life before words, and live submissive to every creature,'" he said.
"In Damietta, St. Francis was not afraid of Muhammad and the Sultan was not afraid of the Gospel, listening to each other. You can also do this too."
Catholic missionaries have established and reestablished a Latin Catholic presence in Iran throughout the past 700 years. Dominicans founded the first Latin Catholic diocese in Iran in 1318, which lasted for less than 100 years. Missionaries returned in 1629 to establish the diocese of Isfahan, which was completely devastated in the 18th century and later entrusted to the bishops of Baghdad.

The cause for beatification of four clerics martyred in Iran was made public earlier this week by the Archdiocese of Paris. Among the martyrs is Archbishop Jacques-Émile Sontag, a former bishop of Isfahan, who was assassinated in 1918 after assisting Christians to flee Kurdistan during the Ottoman massacre.
Sontag's cause for beatification was opened along with those of three other martyred Vincentians: Fr. Dinkha (1849-1918), a Vincentian of the Chaldean Rite, born in Iran to a Muslim family and baptized in secret. Fr. François Mirazis (1878-1918), also a native of Iran ordained as a Vincentian priest; and Fr. Mathurin L'Hotellier, a Vincentian who served as superior of the Salmas mission before he was killed at the age of 35.
The see of Isfahan remained vacant in the decades following World War I until an archbishop of Isfahan was appointed five years before the Iranian Revolution. But the archbishop was expelled from Iran in 1980 after Ayatollah Khomeini gained power.
Ten years later, a Latin Catholic archbishop was once again allowed to reside in Tehran and Bedini was consecrated.
Archbishop Emeritus Bedini concelebrated Mathieu's episcopal ordination along with the Franciscan Cardinal Mauro Gambetti. The ambassador of Iran to the Holy See also attended the ordination.
For his episcopal motto, Mathieu selected "Deus Meus in te confido" ("My God, in you I trust").
Sandri noted in his homily that the Franciscan also added an eight-pointed "Persian star," a symbol in traditional Islamic art, in his episcopal coat of arms. The letters IHS, a monogram symbolizing Jesus, are placed inside of this star, which is situated below the symbol of the Franciscan order.

"Set off, filled with divine grace, for the ancient and noble Persian land, making backwards the journey of the Magi who set out from those areas looking at the stars and looking for the Savior," Sandri said.
"You too are a passionate explorer of the skies, and you wanted to place the 'Persian star' in your coat of arms, a reference to the wisdom of that people and at the same time a reference to Christ and Mary Most Holy."
He continued: "Among the stars that will guide you and intercede for your ministry are certainly that of Mary, Mother of God and our Mother Immaculate Virgin, St. Francis and all the saints of the Franciscan order, the holy Apostles Philip and James, but also St. Maruthas, remembered today in the Roman Martyrology, and the Persian martyrs Abdon and Sennen, whose mortal remains rest a few meters from here in the Basilica of St. Mark."
"They all watch over your path from heaven and make us feel the Christian heart of Iran which beats in the center of Rome, seat of the Successor of the Apostle Peter."
