Presented here general idea of understanding the unity of faith in the Church according to Ipatij Potij (Hipacy Pociej), the Kiev Metropolitan, seems to cast a new light on the very phenomenon of integrating the union into the Ruthenian Church. Potij claimed that the greatest enemy of the uniatic process in Ruthenia are the persons and institutions not interested in serving the Church as the lively centre of spiritual life of the whole society. That is why he developed his own view concerning maintaining of the unity in the Kiev Church after the union was formed, and the permanent bonds of Christianity in Ruthenia with the traditional Eastern heritage and full relationship with the universal dimension of the Church. It was extremely open vision and at the same time filled with creative inspiration.
