There are different kinds of adjectives i.e. attributive, predicative, etc. We sometimes use some adjectives for people but some aren't used in such a way. What about the adjective 'doctrinal'? We can say:

```
doctrinal matters, doctrinal character, doctrinal manuals, etc.

```

Can we use this for people? As in:

**He is a rightly doctrinal person.**

meaning: he believes in/ has the right doctrine.
