The switch is the 'natural' result of spiritual barrenness and dissatisfaction, as Protestant denominations adopt liberal stances and values, for example, legitimizing homosexuality
Another movement that the media fails to bring to your attention: the massive conversions of Protestants to Eastern Orthodoxy, the original form of Christianity.
More than 79% of clergy in Orthodox Churches were previously pastors of various denominations. There have been cases of entire parishes converting to Orthodoxy.
As some pastors-turned-priests explain, the switch is the 'natural' result of spiritual barrenness and dissatisfaction, as Protestant denominations adopt liberal stances and values, for example, legitimizing homosexuality.
These departures from normal Christian morals disappoint people and they start looking for the True Church.
The turning point was 1987 when 2,000 evangelicals from the Dallas Theological Seminary in Texas converted to Christianity.
A Russian bishop, Metropolitan Hilarion Alfeev, interviewed towards the end of the video, explains:
Now in Protestant Churches and the Church of England, processes are taking place which bring believers to the question: Does it even make sense to remain in such a church?
I must say straight out that we do not consider the Protestant Church and the Church of England to be "Churches' in the true sense of the word. Because they don't have, probably the most essential characteristics of the Christian Church. They don't have the true comprehension of the sacraments, they've lost the Apostolic succession of hierarchy. And for the past 10 years, they have undergone such a horrifying process of liberalization that traditional Christian morality is not preached any longer in their churches.'
