To mark the 50th anniversary of the opening of the Second Vatican Council and the 20th anniversary of the publication of the Catechism of the Catholic Church, Pope Benedict has declared a “Year of Faith” to be celebrated beginning from 11th October 2012 until 24th November 2013, the feast of Christ the King.
The Pope declared the Year of Faith with his Apostolic Letter Porta Fidei (published on 11 Oct 2011). You could download a pdf format of the full text from this LINK. If you just want a SUMMARY you could have it as well.
This was followed by the publication of a Note with Pastoral Recommendations for the Year of Faith (dt 6 January 2012) by the Congregation for the Doctrine of Faith. Again, you could download a PDF File or have a look at the SUMMARY of the same.
