The Greek Church Fathers also called it the "All-Virtuous Wisdom", while the Latin Church Fathers, beginning with Cyprian, termed it Ecclesiasticus because it was frequently read in churches, leading the early Latin Fathers to call it liber ecclesiasticus (Latin and Latinised Greek for "church book").

Is Ecclesiasticus different than Ecclesiastes?

Two Books of the Bible, Ecclesiastes, which is within canonized Scripture, was written by King Solomon, and this is the New American Standard version; and Ecclesiasticus, from the Apocrypha or "hidden books", was written by a man named Jesus Sirach, and this is the King James version.

When was Ecclesiasticus removed from the Bible?

This book is from from the 16 apocrypha books of the Bible, it was omitted from the Bible by the Protestant Church in the 1800's. This book is as true today, as it was in the 1800's before being omitted from the Bible.
