Entry: IT IS, unfortunately, a general observation that a large segment of today's Orthodox Christians is not sufficiently informed on matters of faith, worship, and life. They have little knowledge about these issues, sometimes not correct, and even contradictory to what the Church of Christ teaches, based on the Holy Scripture and its long Tradition.

This observation is not ours. It is expressed or stated by official steps of their shepherds and ecclesiastical publications. Bishops have declared before the Hierarchy Synod: "Sermons are being preached, both orally and in writing, but what is happening after all, why is our people ultimately left uninstructed? What is the fault?" (magazine "Church" 2010, p. 405).

"Our people are uninstructed, and let us question again whether this observation honors us, as well as who bears the responsibility for the uninstructed state of our people" ("Church" 2013, p. 171).

Without intending to replace, even in the slightest, our ecclesiastical shepherds in their prophetic work, nor to ignore the existence of very important and multi-page books by great authors who have dealt with the relevant themes (which we recommend for study), in this current Series of brief volumes, we offer to interested clergy – as an aid to their work – and lay readers, a concise "bouquet" of texts, which read easily, are understandable, do not cost much (in a time of crisis) and aspire to provide the necessary knowledge to every Orthodox Christian.
