During the last few years there appears to have been a steady increase in the use of the terms YHWH, and Yehoshua, (or Yeshua) in the SDA church. I do not want to overstate my thoughts here, but it appears to me that one of Jesus’ lessons is sometimes missed in this area.
When the disciples asked Jesus to teach them to pray, one of the first lessons He gave them was how to address God.
He taught them to address God as their “Father.”
For the people that feel it is important to address God in the Hebrew or Greek, perhaps the Hebrew, Ab, or the Greek, Pater, would be more in keeping with Jesus’ teaching.
There is always the danger that technical, “legal”, correctness will miss some of the most simple, but important, lessons.
Obviously it is not wrong to use the names Jehovah, or YHWH, but let's remember Jesus' lesson.
How often do we hear Jesus speaking of His Father?
I have not counted the number, but I doubt that anyone would disagree that it was His common practice.
