Do not be stumped. Tell your Catholic friend to read more bible
or at least attend bible study classes.
Acts 11:
26and when he had found him, he brought him to Antioch. So it was
that for an entire year they associated with* the
church and taught a great many people, and it was
in Antioch that the disciples were first called
Christians.
As you can see, the christian church has already been there at
Antioch, which predates anything your friend can tell you from
their Catholic tradition.
2) They also claim that all christians are protestants. And this
was even further backed up by a former christian.
If Catholics like them have no wish to be associated with
Christians, then I feel sorry for them.
Regardless of what your church tells you, what the tradition tells
you, what your pastor or priest tells you, always remember you
swear allegiance to God.
For it is written,
4There is one body and one Spirit, just as you were called to the
one hope of your calling, 5one Lord, one faith, one baptism, 6one
God and Father of all, who is above all and through all and in all.
(Ephesians 4)
