[4][6] In March 1801 Joseph Tyan wrote an encyclical to his faithful against the Jansenistic doctrine of Germanos Adam, thus defending papal primacy.

[7] He also had to face the discontent of some of his bishops, led by the Khazen Sheikhes, who in 1800 wrote to Rome complaining that Tyan illegally took church properties and instigated discord.

[5] Due to the above difficulties, in 1805 the Vatican appointed an Apostolic visitor in the Maronite Patriarchate, Germanos El Khazen bishop of Damascus, followed on March 7, 1807, by Aloisio Gandolfi, who took a stand against Joseph Tyan, and advised him to retire.

On October 3, 1807, Patriarch Joseph Tyan wrote a letter to Rome with his resignation, that was communicated to the Maronite bishops on November 19, 1808.

[4] Joseph Tyan retired in a hermitage and later moved to Kfarhaye (Batroun District) to teach theology in the newly erected seminary of Saint Maron.
