Matthew Henry is a 5 point Calvinist. I'm not sure if you know what it means, but, in simple terms, he's as strong a Calvinist as one can be (I can explain 5 point Calvinist in more detail, if you prefer). 5 point Calvinism is about as far from Adventism as one can get.

The people see that they have been deluded. They accuse one another of having led them to destruction; but all unite in heaping their bitterest condemnation upon the ministers. Unfaithful pastors have prophesied smooth things; they have led their hearers to make void the law of God and to persecute those who would keep it holy. Now, in their despair, these teachers confess before the world their work of deception. The multitudes are filled with fury. "We are lost!" they cry, "and you are the cause of our ruin;" and they turn upon the false shepherds. The very ones that once admired them most will pronounce the most dreadful curses upon them. The very hands that once crowned them with laurels will be raised for their destruction. The swords which were to slay God's people are now employed to destroy their enemies. Everywhere there is strife and bloodshed. {GC 655.4}

The mark of deliverance has been set upon those "that sigh and that cry for all the abominations that be done." Now the angel of death goes forth, represented in Ezekiel's vision by the men with the slaughtering weapons, to whom the command is given: "Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at My sanctuary." Says the prophet: "They began at the ancient men which were before the house." Ezekiel 9:1-6. The work of destruction begins among those who have professed to be the spiritual guardians of the people. The false watchmen are the first to fall. There are none to pity or to spare. Men, women, maidens, and little children perish together. {GC 656.2}

"The Lord cometh out of His place to punish the inhabitants of the earth for their iniquity: the earth also shall disclose her blood, and shall no more cover her slain." Isaiah 26:21. "And this shall be the plague wherewith the Lord will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand upon their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth. And it shall come to pass in that day, that a great tumult from the Lord shall be among them; and they shall lay hold everyone on the hand of his neighbor, and his hand shall rise up against the hand of his neighbor." Zechariah 14:12, 13. In the mad strife of their own fierce passions, and by the awful outpouring of God's unmingled wrath, fall the wicked inhabitants of the earth--priests, rulers, and people, rich and poor, high and low. "And the slain of the Lord shall be at that day from one end of the earth even unto the other end of the earth: they shall not be lamented, neither gathered, nor buried." Jeremiah 25:33. {GC 656.3}

The command is, "Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at My sanctuary. Then they began at the ancient men which were before the house." Saith God. "I will recompense their way upon their head." {TM 431.3}

The words will soon be spoken, "Go your ways, and pour out the vials of the wrath of God upon the earth." One of the ministers of vengeance declares. "And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because Thou hast judged thus." These heavenly beings, in executing the mandate of God, ask no questions, but do as they are bid. Jehovah of hosts, the Lord God Almighty, the just, the true, and the holy, has given them their work to do. With unswerving fidelity they go forth panoplied in pure white linen, having their breasts girded with golden girdles. And when their task is done, when the last vial of God's wrath is poured out, they return and lay their emptied vials at the feet of the Lord. {TM 432.1}

You have lost the vast distinction between the Creator and the creature. And to make to make Hitler's relationship to his subjects analogous to God's relationship to His subjects is mind-boggling.

Furthermore, to disallow every instance that does not fit into your paradigm as irrelevant makes it very easy to accept any paradigm that suits your fancy. The trick is to find a paradigm that fits all the facts.

...
When the destroying angel was to pass through Egypt, to destroy the first-born of man and beast...

...the rage of the wicked multitude was turned upon each other.

Do you agree that a holy angel sent by God caused Herod great agony of mind and body?
