Perhaps you're conflating faith with religion.

Faith being "confidence, trust or belief in a thing , person or concept, sometimes in the absence of proof"

Not to be confused with "blind faith" which is the above but with wilful ignorance or dismissal of proof that contradicts the aspect of the faith.

Also not to be confused with "religion" which is the social construct or organisation around a central faith.

You can have faith without religion, but you can't generally have a religion without faith.

I am not conflating faith with religion, but the statement clearly refers to his religion...MacIntyre appeals and arguments smuggle theology in through the back door.

Presents basic commitments as if they were simply the unavoidable presuppositions of moral reasoning, yet in practice the basic commitments he privileges are those of Roman-Catholic Thomism. By treating them as axiomatic rather than doctrinal...transforms a Catholic moral vision into what looks like a neutral starting point.

Disguises an apologetic project as pure philosophy.

“At the foundation of moral thinking lie beliefs in statements the truth of which no further reason can be given.” ― Alasdair C. MacIntyre, After Virtue

I will defer to your superior knowledge of his actual writing, i haven't read them, i was referring purely to your reply to the statement provided.

The quote mentioned faith and philosophy by name, if the actual writings are more about religion than faith then i retract my statement.

To be clear, i'm not religious nor do i have much in the way of faith.

I just don't think faith and philosophy are mutually exclusive.

My impression of organised religion is unfavourable so I'm almost certainly biased in my perspective of religion being the reason faith gets such a bad reputation.

This is a very common stance in the Roman Catholic Church. The concept of “faith and reason” as two sides of the same coin both leading to truth is a pretty major teaching in the church these days.
