James 2:7

‘Do they not blaspheme the honourable name by which you are called?'

Indeed, he can go further. It is the rich and the powerful who more than any others bring the name of Jesus into disrepute. And they openly blaspheme (use abusive and scurrilous language) against His Name, insulting His Name in public, treating it with contempt, that Name ‘by which His people are called' (whether as Messiah-nists, or as Christ-ians (1 Peter 4:14; 1 Peter 4:16; cf. Acts 26:28), or as Jesus' people, or whatever). But in the end to be ‘called by His Name' was to be set aside as precious and under His care (see Amos 12:9, and compare Jeremiah 14:9). There may be the thought here that Jesus Name was called over them when they were baptised after coming to repentance.
