The true church is a spiritual entity consisting of all believers, not a worldwide denomination. When Catholic ask for an alternative to the Roman Catholic Church, an alternative that would be a worldwide denomination, that could trace itself back to the apostles through successors, etc., .....they're asking for an alternative where there shouldn't be one.

I Peter 2:4-5
To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious, Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.

As Paul said, we are many members of the one Body of Christ because we share in the One Bread.

1 Corinthians

Paul believed in the Eucharist and Christ present in it.
