Since enlightenment of God Word comes from the Father (Luke 10:21), wouldn’t it be wise to obey His Son?
Especially, even more so, if they think He is God?
The vast majority of Christendom — denominations I mean, most of whom are Trinitarian — while claiming obedience to Christ (who commanded His followers to 'love their brothers' - John 13:34-35), have
killed their brothers during worldly conflicts, supporting nationalism over their spiritual brotherhood.
Titus 1:16 applies to them.
In fact, Christians shouldn’t be involved in killing
anyone. There is never justification for planned killing. — Matthew 5:44
Am I exaggerating Christendom’s participation in wars? I don’t think so....
Catholic historian E. I. Watkin acknowledged: “Painful as the admission must be, we cannot in the interest of a false edification or dishonest loyalty deny or ignore the historical fact that Bishops have
consistently supported all wars waged by the government of their country. I do not know in fact of a single instance in which a national hierarchy has condemned as unjust any war . . . Whatever the official theory, in practice ‘my country always right’ has been the maxim followed in wartime by Catholic Bishops.”

Protestant clergyman Harry Emerson Fosdick admitted: “Even in our churches we have put the battle flags . . .
With one corner of our mouth we have praised the Prince of Peace and with the other we have glorified war.”

Columnist Mike Royko of the Chicago Tribune wrote: "Nor have Christians ever been squeamish about waging wars on
other Christians. If they had been, most of the liveliest wars in Europe would never have occurred.”

Anne Fremantle wrote in the book Age of Faith: “Of all the wars men have waged, none have been more zealously undertaken than those on behalf of a faith. And of these ‘holy wars,’ none have been bloodier and more protracted than the Christian Crusades of the Middle Ages.”

(I can provide more references.)
Jesus stated @ Matthew 7 18, “By their fruits you will recognize them.” In vss 21-23, Jesus even said He would deny those doing “powerful works” in his name.
The Apostle John, @ 1 John 3:10-15 (NIV), was imo even more forceful:
“This is how we know who the children of God are and who
the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone
who does not love their brother and sister.
“For this is the message you heard from the beginning: We should love one another.
Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. Do not be surprised, my brothers and sisters, if
the world hates you. We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.”
My point is, if they’re willfully disobedient, should you expect them to have Scriptural enlightenment? Should you trust their theology?
It’s strong language, but hope it will reach your heart.
