The original name for Jesus in Hebrew-Aramaic is yeshu‘a. This was translated into Greek as Iēsous and then via the Latin Iesus into German, and eventually into English as Jesus.
Since Christians believe that using the name of Jesus/Yeshua in prayer adds authority and power, it could be argued that Christians should be using his original name (Yeshua) or at least something closer to it, rather than the somewhat convoluted translation "Jesus".
Are there any denominations or Christian groups that use "Yeshua" as opposed to "Jesus"?
Is there any evidence that other denominations have considered changing their usage from "Jesus" to "Yeshua" and are there any documented reasons why that suggestion was rejected?
