orthopraxy

Meanings

1. Correctness of practice or action in regard to religion and especially religious ritual, particularly in juxtaposition to "correct doctrine", or "correct belief" (that is, "orthodoxy").
2. Right belief combined with right practice, with the emphasis on the latter, often in Latin American liberation theology, contrasting with an orthodoxy seen as insufficiently interested in the practical and political content of faith.

Etymology

A modern, nineteenth century derivation mimicking that of Ancient Greek ὀρθοδοξία (orthodoxía), using the stems of ὀρθός (orthós, “correct”) + πρᾶξις (prâxis, “action, deed; conduct, practice”), and the English suffix -y creating abstract nouns.
