Mother Angelica was and is a living Saint for us in the 21st century.  If you really want to understand the true essence of the Catholic faith watch Mother Angelica Series which are frequently aired on EWTN channel.  Mother Angelica was and continues to be a great teacher for us along with saintly Archbishop Fulton Sheen, whose series continue to bring us great hope and truth through studying holy scripture(the Bible) offering everyone the chance to know and believe in the rock solid foundation of the catholic faith.  In our lifetime they both greatly served us and our Lord inspiring great truths that have fulfilled  Gods plan and served us greatly as true living role models for Christ Jesus and their truths and they both leave behind the most amazing legacy one that will continue beyond our lifetime. One that is there for anyone seeking to know and understand their true identity and purpose in life.  It has been my experience personally through great trials and many errors, as Saint Augustine reminds us of this truth: "Our hearts do not rest -until they rest in (Thee), Jesus himself.
