Johannah,

This is an interesting question.

But, if you make this assertion that we should call Jesus, only Y'shua , or ...?, then we must apply this line of reasoning to the rest of the Word of God-for He is the Word . Are you saying you desire sermons in Greek, Hebrew, and Aramaic?

Additionally, we could only evangelize individuals in Greek, Hebrew, and Aramaic.

Is God the author of languages ? Does He allow the use of other languages?

Acts 2:1-8 And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue, wherein we were born?
Actually, Scripture has SEVERAL names for Christ. One site has nearly 600 listed (we may not agree with all these...). Are not these His names as well?
