A question appeared to me, and I think I know the answer, but I can not find any conclusive source to convince me. Why the word “God” and all pronouns related to it are written with capital letters in both the Bible and the usual practice. I guess people wanted to distinguish the uniqueness of God from other gods, but maybe in the original language of the Bible it is also written with capital letters.
The Old Testament was written in Hebrew. In this language they are writing from right to left and there are no capital letters, even more, there were no vowels initially, but they were added later for the exact reading of the text.
The New Testament was written in Greek, “Koine” (i.e. popular) dialect and there were used only capital letters, i.e. there were no small letters.
Thus, neither in the Old nor in the New Testament was made any difference when writing the word “God” or the pronouns that refer to Him.
Why then they are written with capitals letters nowadays? Because in our language there is the concept of capital letters and all proper names are written so. To draw attention to the divinity of God, the Lord Jesus Christ and the Holy Spirit, it was found proper to use capital letters not only when writing names, but also the pronouns, that explain the Holy Trinity. I do not know details when these spelling rules were established, but I invite readers to write at the comments the information they know.
