The Evolution of the Uniateism Doctrine in the Context of the Vatican's Eastern Policy at the End of the 19th and early 21st Centuries
The desire to overcome the split of Christianity in 1054, which laid the foundations for the formation of two religious systems - proclamation and Catholicism, initiated the signing of the Lyons (1274), the Ferraro-Florentine and Berestea Unions, which created a special model of the Church. Subsequently, such Churches felt the pressure of Romanization, which further strengthened the Orthodox persuasion of the desire of the Apostolic See to subordinate the Orthodox Church. The mutual alienation between the Catholics and the Orthodox was deepened in the eighteenth century, when the Congregation for the Spread of Faith by the special decree in 1729 banned "communication in sacris" (joint worship and participation in the Holy Sacraments). The doubts of the Catholics in the grace of the Orthodox churches had a reciprocal reaction from the patriarchs of Constantinople, Alexandria and Jerusalem, who in 1755 issued a joint statement calling them heretics all who were outside the Orthodox Church.
