I find it amazing that anyone would try to throw out a red herring by claiming that abolitionists and the northern states were abandoning Bible-believing Christianity.
No, the white Protestants in the Old South were not spiritually superior to the Christians in the northern states.
To the Christians in the north, Bible-believing Christianity called for the end to slavery.
Regarding the existence of slavery in the original 13 states, that slavery was eliminated in the northern states due (at least in part) to northern Christians seeing slavery as being contrary to the commandment to love your neighbor as yourself.
When the U.S. Declaration of Independence was first drafted, it contained a complaint about the existence of slavery in the English colonies.
Here is what the
rough draft says:
Indeed, in its final form, the most famous sentence in the U.S. Declaration of Independence is this:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
Slavery, in the eyes of the northern Christians, conflicted with the rights that God had given to every person.
Unfortunately, in 1776, the pursuit of independence from England and, in 1787, the need to ratify the U.S. Constitution required cooperation from the southern states. In order to get that cooperation, the northern Christians had to tolerate the existence of slavery until there came a better time to challenge the existence of slavery anywhere in the USA.
To their advantage, the northern states were able to eliminate slavery on a state-by-state basis during the antebellum period.

Now, regarding what God did for me . . .
He purchased my redemption so that I could be His earthly adopted child, not His earthly slave.

Also, servants are not identical to slaves.
The label "Master" does not always refer to a slave owner. Sometimes the label refers to one who is an employer, a teacher or a superior.
For example, in the
Batman movies, Alfred the butler calls his employer "Master Bruce". Alfred is Bruce Wayne's employee, not his slave.
Likewise, in the
Star Wars movies, "Master" is a rank among the Jedi, as well as what a Jedi apprentice calls his/her Jedi teacher.
So, whenever the word
Master is used in
Matthew,
Mark,
Luke and
John, the word isn't necessarily referring to someone who owns slaves. Instead, the word refers to a landowner who employs people to be his servants.
