It's nice to agree with the patriarch in his assessments. Unless one can doubt that “carnal godlessness, coming simply from instinct,” is something new. It seems that people have been complaining about this problem for thousands of years, and it always seems that the current times are worse than any previous ones.
But it’s true: making the faith of at least the majority of those who consider themselves Orthodox an essential part of their worldview is “a very difficult task.” Most likely, even insoluble in the modern world, if you try to achieve real religious unanimity - well, so that this majority dogmatically correctly judges the Trinity, for example, or rejects elements of other religions.
For the majority to motivate their actions with religious considerations is a task that is at least a little more realistic. Not in the sense of achieving universal righteousness, but in the sense that rational motivations would include religious elements, as was the case with people before the era of secularism. This happens in our time - see, for example, examples of religious revival in a number of Muslim countries.
And while nothing like this is happening, it is indeed difficult to call our people Orthodox in any real sense. It is good that Patriarch Kirill came to such an understanding; Previously, judging by his speeches, he thought differently.
Could this happen? It's unlikely, but in principle it can. But it is unlikely that such a change in the “values of the people” can occur without the promotion of corresponding political ideas. And it is unlikely that Patriarch Kirill does not understand this.
