We should refer to God in the manner God wants us to refer to God (not using a pronoun here intentionally).
The first time we see a pronoun for God is in Genesis 1:5 (NASB)
1:5 God called the light day, and the darkness He called night and there was evening and there was morning, one day.
Now one might say that this is how Moses (considered the author of Genesis) referred to God.
So we can look at how each Person of the Trinity referred to the other. Let's refer to them as the 1st, 2nd and 3rd persons of the Trinity.
1st Person sends a message about 2nd Person through an angel to Joseph:
Matthew 1:21 "She will bear a Son; and you shall call His name Jesus,
for He will save His people from their sins." (NASB)
2nd Person (named Jesus) speaks about the 1st Person as "Father":
Matthew 5:45 so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.
2nd Person speaks about the 3rd Person (Holy Spirit - see below) and refers to "He" and "Him":
John 14:26 "But the Helper, the Holy Spirit, whom the Father will send
in My name, He will teach you all things, and bring to your
remembrance all that I said to you.(NASB)
Further, per the complete revelation of the Bible, Christ will come back for wedding His corporate bride (Rev 19:7). And He is the bridegroom (John 3:29).
