What was the function of the new baptismal office in the second half of the 18th century?

Formed in 1740, the Christian mission for non-Russian peoples who lived in the Volga region (Mordovians, Chuvashs, Cheremis, Votyaks, Tatars) was called the Novokreschensk office.
The basis for the creation of the aforementioned office was the Commission for New Baptism Affairs, which appeared in 1731. In order to encourage the adoption of the Christian faith, the newly baptized were given cash bonuses and freedoms from conscription. The Russification of the Nizhny Novgorod province was facilitated by the work of the Novokreschensk office. The brotherhood of St. Guria became the heir of the Novokreschensk office.
