also, I like the reading of Genesis 3:15 in the Douay Rheims. check it out. nope Abraham did not have a Church. there is no indication he even kept the sabbath, or the rest of the mosaic law, since God had not given it yet. Israel is never refered to as a Church in the O.T. if im wrong, show me where you find this word to describe them. thx

also you can check out romans 11:11-32. pay special attention to verses 25 thru 27. Im sure you will gloss over these, since i believe the Adventist suffer from a similar blindness. but feel free to examine and give an answer, as always i welcome them. Peace
Genesis 2
1Thus the heavens and the earth were finished, and all the host of them.
2And **on the seventh day God ended his work **which he had made; and he rested on the seventh day from all his work which he had made.
3And
God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
Ex.20
8Remember the sabbath day, to keep it holy.
9Six days shalt thou labour, and do all thy work:
10
But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
11For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
The seventh day rest was given at creation, “the seventh day is the sabbath of the LORD thy God”
Gen.26
5Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.
Abraham kept the commandments of God, including the Sabbath commandment.
Jeremiah 6
2I have likened the daughter of Zion to a comely and delicate woman.
The daughter of Zion, God’s church, is likened unto “a comely and delicate woman” in
Jer.6:21.
2 Corinthians 11
1Would to God ye could bear with me a little in my folly: and indeed bear with me.
2For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
A chaste virgin in 2Cor.
Eph.5
22Wives, submit yourselves unto your own husbands, as unto the Lord.
23For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
Rev.19
7Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.
8And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints.
A wife in Eph. 5 & Rev.19
This is the same woman mentioned in Gen3:15 and Rev.12:17
17And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Isaiah 51
1Hearken to me, ye that follow after righteousness, ye that seek the LORD: look unto the rock whence ye are hewn, and to the hole of the pit whence ye are digged.
2Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him.
3For the LORD shall comfort Zion: he will comfort all her waste places; and he will make her wilderness like Eden, and her desert like the garden of the LORD; joy and gladness shall be found therein, thanksgiving, and the voice of melody.
4Hearken unto me, my people; and give ear unto me, O my nation: for a law shall proceed from me, and I will make my judgment to rest for a light of the people.
5My righteousness is near; my salvation is gone forth, and mine arms shall judge the people; the isles shall wait upon me, and on mine arm shall they trust.
6Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished.
7Hearken unto me, ye that know righteousness, the people in whose heart is my law; fear ye not the reproach of men, neither be ye afraid of their revilings.
8For the moth shall eat them up like a garment, and the worm shall eat them like wool: but my righteousness shall be for ever, and my salvation from generation to generation.
9Awake, awake, put on strength, O arm of the LORD; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab, and wounded the dragon?
10Art thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over?
11Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.
12I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass;
13And forgettest the LORD thy maker, that hath stretched forth the heavens, and laid the foundations of the earth; and hast feared continually every day because of the fury of the oppressor, as if he were ready to destroy? and where is the fury of the oppressor?
14The captive exile hasteneth that he may be loosed, and that he should not die in the pit, nor that his bread should fail.
15But I am the LORD thy God, that divided the sea, whose waves roared: The LORD of hosts is his name.
16And I have put my words in thy mouth, and I have covered thee in the shadow of mine hand, that I may plant the heavens, and lay the foundations of the earth, and say unto Zion, Thou art my people.
I ask you to read this passage from Isaiah. Is this not talking about God’s church?
