He assisted in the glorification (canonization) of some of the Russian saints, ordering the celebration of the memory of Basil Fool for Christ in 1588, as well as that of Joseph Volotsky and others. Patriarch Job also favored the construction of new cathedrals and monasteries and Christian missionary activities in the recently conquered Astrakhan Khanate and Siberia. He also corresponded with Catholicos Nicholas V of Georgia and exchanged gifts with him. After the mysterious death of tsarevich Dmitry Ivanovich in 1591, Job accepted the non-criminal version of his demise, supporting Boris Godunov every step of the way.
