Muffled
Jesus in me
It might be more appropriate to refer to the Roman church - or the church of Rome.
The true church, consisting of all who believe (with living faith), had always been 'catholic' meaning the church is one, undivided Christian church with historical continuity from when the first church started.
To say someone is Catholic is actually a misnomer. The true church (the community of faithful believers) is catholic, a person is not catholic.
Church membership does not equate to salvation. Membership in the Roman Catholic church (or any other denomination) is not a passport to heaven - salvation is by faith alone. In other words, only those declared righteous by God because of their faith are part of the one and only church.
I was watching an episode of Medici on Netflix and the Pope ordered his priests in Florence to not baptize babies which was a consternation because any unbaptized babies would go to Hell. That is so unbiblical that it would be laughable if it were not so much a cause of distress.
