Answer:
Given the word choices on the comments section of your question, and given the structure of the paragraph, the first thing I will do is tell you what each word means, and then organize them inside the sentence. I hope that this helps.
Piety: its the quality of being religious or devoted to a religion or system of belief.
Doctrine: It is the codification of the beliefs, or the teachings that are present in a religious system of belief.
Deity: It is a higher being, or higher power in which a religion or system of belief may believe in.
Zeal: The enthusiasm with which something is pursued, or a goal is met.
As such, the paragraph would be organized in this manner:
Cyril is a very pious monk. He devotes his life to religion and earnestly follows the doctrine of his church. He is not interested in zealous matters, which he regards as distractions from the worship of the Deity that he believes in.
The order of these words comes from following the logic within the structure of the paragraph itself and you also use the clue words within the paragraph to guide you in organizing the words and putting them in their correct grammatical form.
