In the 16th century, world Christianity experienced a series of military conflicts. The churches sought to supplant each other. Humanity entered the age of Enlightenment: religion was subjected to harsh criticism and denial. The search for new models of human consciousness, independent of Biblical doctrines, began.

Innovators opposed the progress of Christianity-a gradual development, the transition from simple to complex. Based on the idea of progress, Darwin would later develop a theory of evolution based on scientific facts. According to it, man is not a creation of God, but the result of an evolutionary process. Since the 17th century, science and religion have been in continuous conflict.

In the 20th century in the post-revolutionary Soviet Union, Christianity is experiencing a period of strict prohibitions and categorical denial of the religious view of the world. The Ministers of the churches refuse to Sana, churches are destroyed, and religious books burned. Only with the collapse of the USSR religion gradually regained its right to exist, and freedom of religion became an inalienable human right.

Modern Christianity is not a totalitarian religious belief. Christians are free to accept the rite of baptism or refuse to follow its traditions. Since the mid-20th century, the idea of reuniting the three faiths into a single belief has been promoted as an attempt to avoid the extinction of religion. But no Church is taking concrete action and the denominations are still divided.
