The record was uncovered by Third Man archivist Ben Blackwell, who found that "AR 1331 A" is the pressing plant code from Archer Records (hence "AR"). The single in question comes from Cleveland-based Apostolic church the Original Glorious Church of God in Christ.
It's a 7-inch with two tracks on the A-side ("I Want the World to Know Jesus" and "God's Going to Destroy This Nation" ) and two more on the flip ("The Hypocrite" and "Come Out of the Valley").
The single is very obscure and doesn't seem to be anywhere online. Some Google sleuthing turned up a Facebook post from a few years ago and an expired product listing. A copy sold on eBay for $183 USD back in 2016. Who knows — perhaps Kanye West was the buyer.
It's unclear why exactly Kanye put the serial code on Jesus Is King. Perhaps it's simply a hat-tip to a gospel record he found inspirational.
Third Man archivist and Detroit music historian Ben Blackwell has cracked the code on the mystery of what "AR 1331 A" means on Kanye's "Jesus Is King" artwork. It's the Archer Records (AR) pressing plant code assigned to this 1970 Detroit gospel single. @kanyewest @KimKardashian pic.twitter.com/ChOn1S4eZc— Third Man Records (@thirdmanrecords) November 1, 2019
