Katholikos is a combination of two Greek words: kata meaning according to or throughout, and holos meaning whole or complete. Thus, Catholic originally meant according to the whole or universal. The suffix -ly is added to form an adverb, resulting in Catholicly, which means in a Catholic manner or according to Catholic principles.
