circumcised Jews. But "the Jews" (per the Sacred Scriptures), rejected Jesus, their Messiah, and put Him to death.
The Apostles spoke against "the Jews".

The Church was called "catholic" (universal), at least by 107 AD, and likely much sooner.
One of the things Peter did before he went to Rome was to found the church in Antioch, the third largest city in the Roman Empire at the time. He ordained a disciple there named Evodius to the episcopacy and appointed him the bishop of Antioch. Evodius is believed by many to have been one of the seventy disciples Jesus appointed to go ahead of him to the towns and places where he taught during his second missionary journey (see Luke 10:1). It was during Evodius’s reign as bishop of Antioch that the disciples there were for the first time called Christians. But this isn’t the end of the story!
While Paul was teaching the Christians in Antioch during Evodius’s reign, another young disciple was moving up through the ranks. His name was Ignatius, and he would later become known as Saint Ignatius of Antioch, an early Christian martyr. Ignatius was a disciple of John.
At Antioch, Ignatius was ordained by Paul, and then, at the end of the reign of Evodius, he was appointed bishop of Antioch by Peter. He reigned there for many years before his martyrdom in Rome. On his way to Rome to be martyred, he wrote several letters to fellow Christians in various locations, expounding on Christian theology. He especially emphasized unity among Christians (see John 17) and became known as an Apostolic Father of the Church.
In one of his letters (to Christians in Smyrna), he wrote, “Where there is Christ Jesus, there is the Catholic Church.” This is the earliest known written record of the term “Catholic Church” (written around A.D. 107), but Ignatius seemingly used it with the presumption that the Christians of his day were quite familiar with it. In other words, even though his is the earliest known written record of the term, the term likely had been in use for quite some time by then, dating back to the time of the apostles.
