You avoided both Romans 10:13 and Joel 2:32.No, I will hopefully never, ever confess Jesus as YHWH. I feel that it is blasphemy to do so, and then, of course, one cannot be said if they do.
Appellations can be shared amongst various entities. Cyrus was called messiah (anointed one), Moses was called god, God is called a rock, King David was a saviour to his people, etc (1 Corinthians 8:5). One cannot correlate identities simply because two different entities, are addressed by the same title. This goes without saying. You can have many presidents, many CEOs, many lords, many saviours. The jurisdiction varies and determines the potency of each. God is the creator of the universe and all that it contains, Jesus has been conferred all authority and power to rule over it, as God's beloved Son. Again, there are no distinctly reserved words for God in Scripture outside of the specific spelling YHWH, not ehyeh. Therefore, we cannot define who or what a person is in the Bible, simply by their title. Biblical context and one's domain determines the authority, and thus, the entity, of the person.
Can you interpret both passages since Paul is quoting Joel 2:32 and declaring Jesus is the Lord of Joel 2:32 one must confess to be saved.
