Yes!
We absolutely believe in a two-house theology as scripture bears this out, however we do not believe that the houses (called Ephraim) is painted with a broad stroke in that it is/has become the “gentile Sunday church” in general that we see today. We believe the scriptures clearly show that (Ephraim) has no true way to know who he is, however, HaShem says in Hosea 7:8
8 Ephraim, he hath mixed himself among the people; Ephraim is a cake not turned.
Here we see Ephraim is described as a mixed believer, that is they Profess a belief in HaShem yet they worship pagan false gods as well. Rendering Ephraim of no value. Non the less we see the grace and mercy of HaShem through His Son Y’shua and have this prophetic promise from our Elohim in Jeremiah 31:7-10
7 For thus saith the HaShem (יהוה) ; Sing with gladness for Jacob, and shout among the chief of the nations: publish ye, praise ye, and say, O HaShem (יהוה), save thy people, the remnant of Israel.
8 Behold, I will bring them from the north country, and gather them from the coasts of the earth, and with them the blind and the lame, the woman with child and her that travaileth with child together: a great company shall return thither.
9 They shall come with weeping, and with supplications will I lead them: I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble: for I am a father to Israel, and Ephraim is my firstborn.
10 Hear the word of the HaShem (יהוה), O ye nations, and declare it in the isles afar off, and say, He that scattered Israel will gather him, and keep him, as a shepherd doth his flock.
Furthermore, we do NOT believe this is a subtle form of Supersessionism (Replacement Theology) but rather describes HaShem’s true desire and reestablishes the covenant as a renewed covenant by Y’shua HaMashiach by His atoning work of his death and resurrection.
