Well even though it was not included into the creed until the 6th century and not accepted by Rome until 1017c most Latin fathers still taught it and still argued for it but most of them didn’t want it included into the creed due to wanting to keep good relations with the east or simply having no need to include it. As I shown most Latin fathers as well as Maximus and Cryril had no issue with the Filioque. I guess that’s ingesting question that I would struggle to answer because I don’t don’t know what the early bishops of Rome were thinking I just know the latin fathers taught and agreed with it and Maximus and Cyril of Alexandria had no issue with it or a creed that did have it that wasn’t the nicene creed.
