What does Trinitarian Protestantism understand by salvation being in the name of 'Jesus Christ of Nazareth'?

Peter had the following words to say to the rulers, elders and scribes in Jerusalem regarding the healing of the lame man at the temple : >... the name of Jesus Christ of Nazareth ... neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. > >[Acts 4: 10, 12 KJV] What is understood by Trinitarian Protestantism that salvation is by the 'name' of Jesus Christ and, more specifically, by the name 'Jesus Christ of Nazareth' ? Do Protestants understand that this is a matter of 'identification' possibly, or a matter of 'location', that is to say identifying and locating God himself in his manifestation in the Person of the Son of God ? Is this, according to Trinitarian Protestantism, a matter of identifying and locating the one true God that one might call upon **him (and him only)** for salvation ? It is noticeable that the apostle does not say 'Jesus Christ of Bethlehem', but 'Jesus Christ of Nazareth'. Does Trinitarian Protestantism have any light to shed upon this ?
