Malachi 3 in the early church

“Behold, I will send My messenger, who will prepare the way before Me. Then the Lord whom you seek will suddenly come to His temple—the Messenger of the covenant, in whom you delight—see, He is coming,” says the LORD of Hosts.

But who can endure the day of His coming? And who can stand when He appears? For He will be like a refiner’s fire, like a launderer’s soap.

And He will sit as a refiner and purifier of silver; He will purify the sons of Levi and refine them like gold and silver. Then they will present offerings to the LORD in righteousness.

“Then I will draw near to you for judgment. And I will be a swift witness against sorcerers and adulterers and perjurers, against oppressors of the widowed and fatherless, and against those who defraud laborers of their wages and deny justice to the foreigner but do not fear Me,” says the LORD of Hosts.

“Because I, the LORD, do not change, you descendants of Jacob have not been destroyed.

Yet from the days of your fathers, you have turned away from My statutes and have not kept them. Return to Me, and I will return to you,” says the LORD of Hosts. “But you ask, ‘How can we return?’

Will a man rob God? Yet you are robbing Me! But you ask, ‘How do we rob You?’ In tithes and offerings.

“Then all the nations will call you blessed, for you will be a land of delight,” says the LORD of Hosts.

“Your words against Me have been harsh,” says the LORD. “Yet you ask, ‘What have we spoken against You?’

You have said, ‘It is futile to serve God. What have we gained by keeping His requirements and walking mournfully before the LORD of Hosts?

So now we call the arrogant blessed. Not only do evildoers prosper, they even test God and escape.’”

At that time those who feared the LORD spoke with one another, and the LORD listened and heard them. So a scroll of remembrance was written before Him regarding those who feared the LORD and honored His name.

“They will be Mine,” says the LORD of Hosts, “on the day when I prepare My treasured possession. And I will spare them as a man spares his own son who serves him.

So you will again distinguish between the righteous and the wicked, between those who serve God and those who do not.”
