Reformed,
Suppose you wipe the scales from your eyes and re-read this:
Remember that the church you seek to reform in the 21st century did not exist until the 16th century.
Remember that in the 16th century, certain men (not Christ, ie: false christs) created new churches in their failed attempt to “reform” the, One, existing Church. Open your eyes man. Read the “Word.” See the truth that is right in front of you.
I believe in remnant theology. Therefore, God’s people were chosen before the foundation of the world, and did not start 500 years ago. It traces back to Abraham and even farther back then that. The gospel was foretold at the fall of mankind in the garden. The remnant chosen by grace can be found in each generation of redemptive history. The Roman Catholic Church is new as compared to the remnant which is much much older.

There are some elect Catholics who makeup part of the remnant of God too (invisible church). I believe the Protestant Reformers were the remnant of God who were called out of the Roman Catholic Church. I also believe that there is only one people of God, with much continuity between the OT and NT. The Old Testament Saints were saved by Christ too, and are united to Him.
I ask, then, has God rejected his people? By no means! For I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin. God has not rejected his people whom he foreknew. Do you not know what the Scripture says of Elijah, how he appeals to God against Israel? “Lord, they have killed your prophets, they have demolished your altars, and I alone am left, and they seek my life.” But what is God’s reply to him? “I have kept for myself seven thousand men who have not bowed the knee to Baal.” So too at the present time there is a remnant, chosen by grace. But if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace. - Rom 11
Micah 7:18
God’s Steadfast Love and Compassion
Who is a God like you, pardoning iniquity
and passing over transgression
for the remnant of his inheritance?
He does not retain his anger forever,
because he delights in steadfast love.
Romans 9
God’s Sovereign Choice
I am speaking the truth in Christ—I am not lying; my conscience bears me witness in the Holy Spirit— that I have great sorrow and unceasing anguish in my heart. For I could wish that I myself were accursed and cut off from Christ for the sake of my brothers, my kinsmen according to the flesh. They are Israelites, and to them belong the adoption, the glory, the covenants, the giving of the law, the worship, and the promises. To them belong the patriarchs, and from their race, according to the flesh, is the Christ who is God over all, blessed forever. Amen.
But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.” This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring. For this is what the promise said: “About this time next year I will return, and Sarah shall have a son.” And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac, though they were not yet born and had done nothing either good or bad—in order that God’s purpose of election might continue, not because of works but because of him who calls— she was told, “The older will serve the younger.” As it is written, “Jacob I loved, but Esau I hated.”
What shall we say then? Is there injustice on God’s part? By no means! For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” So then it depends not on human will or exertion, but on God, who has mercy. For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.” So then he has mercy on whomever he wills, and he hardens whomever he wills.
You will say to me then, “Why does he still find fault? For who can resist his will?” But who are you, O man, to answer back to God? Will what is molded say to its molder, “Why have you made me like this?” Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory— even us whom he has called, not from the Jews only but also from the Gentiles?
