  Examining the role of images in Catholicism

  A very good site which analyses all the different elements of Catholic worship, and an explanation of the different symbols.

  Good analysis of the Catholic understanding of the Eucharist, related to its symbols, drawing on the Catechism of the Catholic Church, and contrasting it with Protestant theology.
