There are differences between trinitarians as to details after this–many or most of us (though not I) would be pretty hesitant to affirm that God loves rebel angels for example and seeks their salvation from sin, even though all of us would quickly affirm that God loves at least some human sinners and seeks their salvation from sin. And although all of us would agree, in principle, that God is the single ultimate Self-existent, Self-begetting, Self-begotten multi-Personal reality, not all of us would agree (though I do) that this means God is essentially intrinsically Love in God’s own fundamental self-existence. And quite a few of us would have problems agreeing that the Spirit proceeds from both the Son and the Father (though I agree with quite a few others of us that the Spirit does not proceed from the Father alone.)
There are some other disagreements among us of this sort; and those disagreements, however little they may seem, are as important as the truth of the ultimate Truth is important! Which is why professionals among us go to a lot of trouble to work on properly identifying and understanding the details. Some of our variances can be reconciled with each other; in other cases we cannot all be right about our variances. But because we care about rightly worshiping and praising God, and about rightly representing God to other people, then we care about those differences. I wish we all cared enough to recognize when our opponents also care about God and are (typically) doing the best they can to love God with all their heart and all their soul and all their strength and all their understanding (even when they have results that are different from ours, and are important enough to disagree even strenuously about!)
But after all, even we theologians are sinners, too. And to a sinner, by corrupted birth and by intentionally chosen habit, disagreement will (naturally!) tend to involve working toward non-fair-togetherness. And even toward regarding non-fair-togetherness as ‘dikaiosune’, righteousness. (Even though that word means… fair-togetherness!–the utter essential reality of God Most High, if trinitarian theism is true.)
