What do the large Christian organisations teach about the origins of the Samaritans?

[The biblical description](https://en.wikipedia.org/wiki/Samaritans#Biblical_versions) of the origin of the Samaritans is that they were moved into Samaria as part of the forced population transfer by the Assyrians after their conquest of the Kingdom of Israel. The Samaritans themselves hold that they descend from the tribes of Ephraim and Manasseh in ancient Samaria, and split theologically at the time of the biblical priest Eli and who remained after the Assyrian deportations. [Modern genetic studies](https://doi.org/10.1002/humu.20077) support the Samaritan narrative that they descend from indigenous Israelites: > Principal component analysis suggests a common ancestry of Samaritan and Jewish patrilineages. Most of the former may be traced back to a common ancestor in the paternally-inherited Jewish high priesthood (Cohanim) at the time of the Assyrian conquest of the kingdom of Israel. What do the large Christian organisations such as the Catholic Church teach about the origins of the Samaritans?
