In 1 Corinthians 9, Paul says,
To the Jews I became as a Jew, in order to win Jews. To those under the law I became as one under the law (though not being myself under the law) that I might win those under the law. 21 To those outside the law I became as one outside the law (not being outside the law of God but under the law of Christ) that I might win those outside the law. 22 To the weak I became weak, that I might win the weak. I have become all things to all people, that by all means I might save some.
So if Paul had a Jewish family over for dinner, do you think he'd pray in Jesus' name?
Or, more close-to-home, if I have my Jewish family members over for dinner, should I be explicit in naming the name of Jesus when I pray? Or, out of respect for the fact that they do not worship Jesus, should I simply give thanks to God without mentioning Jesus?
