Translation of "doctrina" into English

Si es jutgés Agustí i altres escriptors d’acord amb la doctrina catòlica actual, se’ls consideraria heretges.

Augustine and others would be considered heretics if judged according to current Catholic doctrine.

D’altra banda, els baptistes i metodistes s’apressaven amb igual afany a establir les seves pròpies doctrines i refutar totes les altres.

On the other hand, the Baptists and Methodists in their turn were equally zealous in endeavoring to establish their own tenets and disprove all others.

Ara bé, el que cal preguntar-se és: té aquesta doctrina base bíblica?

However, the question must be asked, Is it a Scriptural teaching?
