The commandment against using God in a worthless way is why the Jews don't even REPRESENT God in writing a word for him; hence the G*D. That is an effort at showing respect.3. The God of the Jews and the God of the Christians can't be two different Gods IF there is only one god to begin with. The only conflict is mental and that is why there are sects of Jews (and always have been) and sects of Christianity (and always have been).
The dash in G-d..is nothing about respect and everything about superstition.
What did Jesus tell the Jews?
John 5:46 For had ye believed Moses, ye would have believed me: for he wrote of me.
Who slew the prophets and the Saints? Their own prophets at that.
Can you have the Father without having the Son?
If you are a Christian, the answer is an obvious no.
1John 2:23 Whosoever denieth the Son, the same hath not the Father: [(but) he that acknowledgeth the Son hath the Father also].
In Judaism, there is no Son. There is only YHWH, whoever that is. In Christianity there is a Father, Son and Holy Spirit. His name is Jesus. Or if you prefer, the I AM THAT I AM who spoke to Moses.
Now how in the world can you say that the Judaism and Christianity have the same God when clearly they do not.
