Calvinist double predestination is salvation by election - quite different that the Arminian view.
And I’ve noted the sola scriptura differences on Christology such as held by Oneness Pentecostals. Beliefs on baptism are quite variable as well. These I, and I think a reasonable observer, would term ‘core beliefs’ as the concern one Lord, one faith, one baptism.
I would note, again, that St. Paul did not think this a minor matter.
That’s quite a response to daniel’s lengthy post.
Unconditional election, but both can preach the same "gospel of your salvation," that shuts man up as damned + destitute (and unable to come to God unless the Father draws him), and thus the redeemed are those who repent and believe the simple gospel, trusting the risen righteous Lord Jesus to save them by His sinless shed blood.
And who confess that faith in baptism and following the Lord. The sermons in the book of Acts did not require much of the head, but a broken heart and contrite spirit, as the Lord saves such as believe on the Lord to save them.

So you again resort to this type of response even after i listed multitudinous disagreements in Catholicism. You continually note differences under SS (though the UPC and some others may be seen allowing personal revelation to be equal to Scripture in authority), while ignoring the differences under SE, even in Catholicism, and continue to miss the point.
Do you doubt me? Orthodox apologist and author Clark Carlton: “The Orthodox Church opposes the Roman doctrines of universal papal jurisdiction, papal infallibility, purgatory, and the Immaculate Conception precisely because they are untraditional.” Clark Carlton, THE WAY: What Every Protestant Should Know About the Orthodox Church, 1997, p 135.
Vladimir Lossky, a noted modern Eastern Orthodox theologian, argues the difference in East and West is due to the Roman Catholic Church's use of pagan metaphysical philosophy (and its outgrowth, scholasticism) rather than the mystical, actual experience of God called theoria, to validate the theological dogmas of Roman Catholic Christianity. For this reason, Lossky argues that the Eastern Orthodox and Roman Catholics have become "different men".[18] Other Eastern Orthodox theologians such as John Romanides[19] and Metropolitan Hierotheos[20][21] say the same
Roman Catholicism teaches, also, that, in the Age to Come, man will, with his intellect and with the assistance of grace, behold the Essence of God. The Orthodox declare that it is impossible to behold God in Himself. Not even divine grace, will give us such power. The saved will see, however, God as the glorified flesh of Christ
According to Metropolitan Hierotheos that because the Roman Catholic Church uses philosophical speculation rather that an actual experience of God to derive their theology they are lead into the many errors that Orthodox call into question about their theology including the filioque.[66]
And then you have sects as the SSPX, and also other SE groups that autocratically act like Rome, defining themselves as the one true church. And your assurance that Rome is that church is based upon the premise that she is infallible.
Again both SS and SE can show a basic unity across many groups while having varying degrees of disagreement on deeper levels of the same truths, as well as varying levels of disagreement on other issues, and formal divisions.
Thus the issue remains which is the Scriptural basis.
