There are, of course, many such forms; some of them are so unusual that they are included as a separate line in dictionaries. Your own guesses are not always correct, and not everything can be understood from the context. But still, this difficulty is ultimately overcome by many people who have never found the opportunity to sit down for a course in Church Slavonic grammar: after all, grammar is learned not only and not so much by memorizing declensions and conjugations - it is gradually “deposited” in our memory, in our consciousness and subconscious, if we are immersed in the element of a given language, and this certainly happens with attentive, thoughtful and steady execution of the prayer rule and conscious attending worship services.
In explaining the prayers in this book, we tried to help the inexperienced reader, focusing his attention on some forms of words and grammatical phrases characteristic of the Church Slavonic language. The explanations placed behind the * sign refer entirely to the peculiarities of the language.

To facilitate the first steps, the initial orientation in Church Slavonic texts, we will talk here about some of the most noticeable differences between the Church Slavonic language and modern Russian - about what most often stops an inexperienced reader.
This is in no way a textbook, and certainly not an abbreviated language course - but only something like road signs, telling you which direction to go, or warning against mistakes and dangers.
