I haven't seen other participants addressing your argument, perhaps bec they find them irrefutable. I will attempt to address your points, not hoping to change your mind, but only to show that there may be another plausible point of view.
I don't consider myself a universalist because:
1) I don't believe that all souls go to paradise immediately after death. Only virtuous Christians may have this hope.
2) I don't know whether _all_ souls ultimately experience heavenly bliss or that few may be lost forever.
3) I take the hope that a majority of souls will be saved as a possibility to allay my own anxiety regarding non-Christians and not as a fact to be preached in lieu of the Gospel.
I looked at these passages and have to disagree with this assessment. Exomologeo seems to mean "to profess" or "to acknowledge" as it is often rendered in modern translation. It does not mean to "to confess" under coercion. Php 2:10-11 itself refers to Isa 45:23 where the equivalent Hebrew word, which is shabah, is translated "to swear" allegiance.
The parallels verses Isa 45:23, Rom 14:11, Php 2:10-11, and Rev 5:13 leave no doubt that all (or at least an overwhelming majority) will worship the Lord. This includes those "under the earth" in Hades.
This is , certainly, a common view. I think it goes against the spirit of the passages mentioned above but cannot deny that that interpretation is possible. We'll see if another participant comments on this.
This is talking about the provisional judgment immediately after death. If Jesus cannot forgive his enemies, why would He ask us to forgive our enemies?
Yes, definitely, but is their punishment with absolutely no end? Is everlasting conscious torment the only thing you'd expect for your family members who have lived a virtuous life but did not believe in God and Christ?
The Wrath of God is not unending, it is only until the sinner pays their debt. The Parable of the unforgiving servant is a good example:
The Parable of the Unforgiving Servant
Mat 18:21 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
Mat 18:22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
Mat 18:23 Therefore is the kingdom of heaven likened unto a certain king, which would take account of his servants.
Mat 18:24 And when he had begun to reckon, one was brought unto him, which owed him ten thousand talents.
Mat 18:25 But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made.
Mat 18:26 The servant therefore fell down, and worshipped him, saying, Lord, have patience with me, and I will pay thee all.
Mat 18:27 Then the lord of that servant was moved with compassion, and loosed him, and forgave him the debt.
Mat 18:28 But the same servant went out, and found one of his fellowservants, which owed him an hundred pence: and he laid hands on him, and took him by the throat, saying, Pay me that thou owest.
Mat 18:29 And his fellowservant fell down at his feet, and besought him, saying, Have patience with me, and I will pay thee all.
Mat 18:30 And he would not: but went and cast him into prison, till he should pay the debt.
Mat 18:31 So when his fellowservants saw what was done, they were very sorry, and came and told unto their lord all that was done.
Mat 18:32 Then his lord, after that he had called him, said unto him, O thou wicked servant, I forgave thee all that debt, because thou desiredst me:
Mat 18:33 Shouldest not thou also have had compassion on thy fellowservant, even as I had pity on thee?
Mat 18:34 And his lord was wroth, and delivered him to the tormentors,
till he should pay all that was due unto him.
Mat 18:35 So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses.
Notice that the unforgiving servant was only to receive WRATH UNTIL he paid all that was due to him. Sin is debt, we learn that from the Old Testament. Anytime someone sinned that had certain sacrifices they had to them procure and bring to the altar to make atonement for those sins.
