Canon 661

1. Ecclesiastical permission, expressed only with the word imprimatur, means that the work is free from errors regarding Catholic faith and morals. 2. Approval granted by competent authority shows that the text is accepted by the Church or that the

work is in accordance with the authentic doctrine of the Church.

3. A work that is in addition praised or blessed by the eparchial bishop or a superior authority means that it expresses well

the authentic doctrine of the Church and therefore is to be recommended.
