A catechism is simply a tool for teaching the fundamentals of the faith. Unlike a creed or confession, a catechism uses questions and answers. Many Protestant confessional traditions, like Lutherans, Presbyterians, and Reformed, have used catechisms for centuries. Initially, most catechisms were intended for children.
I always knew in my heart Walt Whitman's mind to be more like my own than any other man's living. As he is a very great scoundrel this is not a pleasant confession.
Confession is something we will never outgrow, even if we become the saints God made us to be. Pope John Paul II and Mother Teresa of Calcutta were revered even during their lifetime; but both made frequent use of the Sacrament of Reconciliation.
I went on a Buddha jag. I read 'Confession of a Buddhist Atheist' by Stephen Batchelor and Karen Armstrong's biography of Buddha, which is a great book.
