Question: "Should all pronouns referring to God be capitalized?"
Answer: Many people struggle with this question. Some, believing it shows reverence for God, capitalize all pronouns that refer to God. Others, believing the “rules” of English style should be followed, do not capitalize the deity pronouns. So, who is right? The answer is neither. It is neither right nor wrong to capitalize or not capitalize pronouns that refer to God. It is a matter of personal conviction, preference, and context. Some Bible translations capitalize pronouns referring to God, while others do not.
In the original languages of the Bible, capitalizing pronouns referring to God was not an issue. In Hebrew, there was no such thing as upper-case and lower-case letters. There was simply an alphabet, no capital letters at all. In Greek, there were capital (upper-case) letters and lower-case letters. However, in all of the earliest copies of the Greek New Testament, the text is written in all capital letters. When God inspired the human authors of Scripture to write His Word, He did not lead them to give any special attention to pronouns that refer to Him. With that in mind, it follows that God is not offended if we do not capitalize pronouns that refer to Him.
If you capitalize pronouns that refer to God to show reverence for His name, fantastic! Continue doing so. If you capitalize pronouns that refer to God to make it more clear who is being referred to, great! Continue doing so. If you are not capitalizing pronouns that refer to God because you believe proper English grammar/syntax/style should be followed, wonderful! Continue following your conviction. Again, this is not a right vs. wrong issue. Each of us must follow his/her own conviction and each of us should refrain from judging those who take a different viewpoint.
