You have to understand that Christianity is supposed to be pseudo-Judaism.
So Jesus was or was not a Jew?
The disciples were - or were not Jews?
Paul was or was not - a Jew?
Rom 2:
28 For he is
not a Jew who is one outwardly, nor
is circumcision that which
is outward in the flesh; 29 but
he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise
is not from men but from God.
Rom 9:6 But
it is not as though the word of God has failed. For
they are not all Israel who are descended from Israel; 7 nor are they all children because they are Abraham’s descendants, but: “through Isaac your descendants shall be named.” 8 That is,
it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants.
Do you really think that this is only agreed to by SDAs???
=========================
Rom 11:
19 You will say then, “
Branches were broken off so that I might be grafted in.” 20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; 21 for if God did not spare the natural branches, He will not spare you, either. 22 See then the kindness and severity of God: to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; for otherwise you too will be cut off. 23
And they also, if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again. 24 For if you were cut off from what is by nature a wild olive tree, and contrary to nature were grafted into a cultivated olive tree, how much more will these who are the natural
branches be grafted into their own olive tree? 25 For I do not want you, brothers
and sisters, to be uninformed of this mystery—so that you will not be wise in your own estimation—that a partial hardening has happened to Israel until the fullness of the Gentiles has come in; 26
and so all Israel will be saved
