So why not use the Biblical term and call Him Jesus?
Seems a lot simpler and that is the way the Holy Bible likes it.
Jesus came so that you could have life, and life more abundantly.
Take up your cross and follow him.
Where does Scripture say that there is to be no reflection, no deepening of understanding of the Faith, no increase of understanding of the IMPLICATIONS of the Faith?
Scripture nowhere COMMANDS that we slavishly use ONLY the phrases that occur in Scripture. Jesus himself tells the apostles that the Spirit will tell them what to say in the future. Note that Jesus doesn’t say, “Just keep repeating EXACTLY the words and phrases that I spoke to you.” No. He says the Spirit would give them NEW THINGS to say.
