What Is the Church? is Regis Martin’s delightful meditation on the beauty and the depth of the Catholic Church. Solidly orthodox and universal in its outlook, this is a work for anyone who wishes to understand more deeply what it means to be Catholic.
In his 1998 encyclical Tertio Millennio Adveniente, Pope John Paul II asked catechists and theologians “to promote a deeper understanding of the ecclesiological doctrine of the Second Vatican Council as contained primarily in the Dogmatic Constitution Lumen Gentium” (no. 47). To respond to this call, Dr. Regis Martin wrote What Is the Church? in order to present a faithful ecclesiology in simple, accessible terms.
