The Catechism of Trent (Unabridged‪)‬

The Catechism of Trent was published in 1566. It was commissioned by the Council of Trent during the period of the counter-Reformation. The document's main task was to clarify the doctrine of the church for the clergy. It enjoyed widespread use within the Roman Catholic world and was considered the authoritative guide for the faithful up until the most recent catechism, which was released in 1992.
