Green cover
The Latin typical edition was published in 1997, with the official English translation.
This edition was the official text of reference, and included a few updates and corrections from the French edition.
To identify this edition, it was given a green cover.
The green-cover Catechism of the Catholic Church corresponds to the 1997 Latin typical edition, which serves as the Church’s definitive reference text. It incorporates final corrections and refinements following earlier versions, including alignment with the French edition. For those seeking the most authoritative and stable presentation of Catholic doctrine, the green edition remains the standard.
