Answer 1

On Pentecost 33 C.E.

Although the Church was not called Christian for 20 or 30 years (according to Acts 11:26 "it was in Antioch that the disciples were first called Christians").

And was not called Catholic for about 70 years.

The Church has referred to itself as the “Catholic Church” at least since 107 C.E. (about 10 years after the last book of the New Testament was written), when the Greek term "Katholikos" (meaning universal) appears in the Letter of St. Ignatius of Antioch to the Smyrnaeans:

"Wherever the bishop appear, there let the multitude be; even as wherever Christ Jesus is, there is the Catholic Church."

We do not know how long they had been using the term "Catholic" before it was included in this letter.

All of this was long before the Council of Nicea and the Nicene Creed from 325 C.E. which states, "We believe in one, holy, catholic, and apostolic Church."
