The Compendium of the Catechism of the Catholic Church is now online in English.
Together with the comprehensive, searchable CCC available from several sources (here’s one), this’ll be a great resource for anyone who wants to know more about the Church and her teachings. It’s slim enough to treat as a reader rather than a reference book.
The Compendium is truly something to get excited about, as the material in it is presented very simply and directly, with the tried-and-true Q&A format. It all fits on one page of HTML! But it retains the structure of the Catechism, which is handy for those who want to turn to the appropriate section in the larger work to find out more.
Here’s a sample entry, from the section that’s based on the sentences and phrases of the Creed.
“Jesus Christ descended into hell;
on the third day He rose again from the dead.”
125. What is the “hell” into which Jesus descended?
632-637
This “hell” was different from the hell of the damned. It was the state of all those, righteous and evil, who died before Christ. With his soul united to his divine Person Jesus went down to the just in hell who were awaiting their Redeemer so they could enter at last into the vision of God. When he had conquered by his death both death and the devil “who has the power of death” (Hebrews 2:14), he freed the just who looked forward to the Redeemer and opened for them the gates of heaven.
The "632-637" refers to paragraph numbers in the larger Catechism. So if you go to the table of contents with paragraph numbers, it’s easy to find the relevant section where you can learn more.
Paragraph 1. Christ Descended into Hell
632 The frequent New Testament affirmations that Jesus was "raised from the dead" presuppose that the crucified one sojourned in the realm of the dead prior to his resurrection. This was the first meaning given in the apostolic preaching to Christ’s descent into hell: that Jesus, like all men, experienced death and in his soul joined the others in the realm of the dead. But he descended there as Savior, proclaiming the Good News to the spirits imprisoned there.
633 Scripture calls the abode of the dead, to which the dead Christ went down, "hell" – Sheol in Hebrew or Hades in Greek – because those who are there are deprived of the vision of God. Such is the case for all the dead, whether evil or righteous, while they await the Redeemer: which does not mean that their lot is identical, as Jesus shows through the parable of the poor man Lazarus who was received into "Abraham’s bosom": "It is precisely these holy souls, who awaited their Savior in Abraham’s bosom, whom Christ the Lord delivered when he descended into hell." Jesus did not descend into hell to deliver the damned, nor to destroy the hell of damnation, but to free the just who had gone before him.
634 "The gospel was preached even to the dead." The descent into hell brings the Gospel message of salvation to complete fulfilment. This is the last phase of Jesus’ messianic mission, a phase which is condensed in time but vast in its real significance: the spread of Christ’s redemptive work to all men of all times and all places, for all who are saved have been made sharers in the redemption.
635 Christ went down into the depths of death so that "the dead will hear the voice of the Son of God, and those who hear will live." Jesus, "the Author of life", by dying destroyed "him who has the power of death, that is, the devil, and [delivered] all those who through fear of death were subject to lifelong bondage." Henceforth the risen Christ holds "the keys of Death and Hades", so that "at the name of Jesus every knee should bow, in heaven and on earth and under the earth." …
IN BRIEF
636 By the expression "He descended into hell", the Apostles’ Creed confesses that Jesus did really die and through his death for us conquered death and the devil "who has the power of death" (Heb 2:14).
637 In his human soul united to his divine person, the dead Christ went down to the realm of the dead. He opened heaven’s gates for the just who had gone before him.
There’s no search utility on the Compendium online, but it’s preceded by a detailed table of contents. And of course, one could work back from the Catechism, using a search utility to find items of interest and then turning to the corresponding passages in the Compendium for the short-and-sweet explanation.
It’s so easy to find out what Catholic doctrine has to say these days. I wish every religious group (at least those that have a well-defined doctrinal system) would put their stuff up online for everyone to see, study, and compare. I don’t just mean holy books, which are rarely self-evident, but rather developed doctrine.
It’s there for a few. For example, here’re some links to the Book of Common Prayer (Anglicans), which of course includes a catechism. The Lutheran Church, Missouri Synod (LCMS) has a very well-organized set of pages that explain their beliefs and practices through documents both new and old. I don’t know of any others.
