It is in Antioch, THE multi-ethnic church, they are first called Christians (Χριστιανούς; Acts 11:26).

For evidence of this multi-ethnic reality, just look to the leaders in Antioch (Acts 13:1)

Additionally the word Χριστιανός is instructive in itself.

it is a Greek word,
of Latin form,
and Semitic background

Previously they have been called saints, disciples, believers, brothers and sisters, the assembly, and the Way.

Now outsiders label them, probably in derision.

A new name is coined for a new identity and mission.
