I think that many things that had to do with the Apostolic Fathers were "credited" to Paul.
Lets not forget what was the core of Paul's teachings:
Love above all, faith in our Lord and Saviour, all are God's children, salvation based on faith in our Lord jesus and not workd done for recompense.
He even reminde people that he was nothing, that the apostles and disciples were nothing compared to Jesus and to receiving Jesus vai the HS.
He said how people were "not baptized under Paul or whoever" but under Our Lord Jesus.
Paul spoke in accordance with his audience and aimed at specififc events even.
With Paul, context was crucial.
We also need to remember that many things written that were acredited to Paul may not have been his writing at all, the case for some of the harsh thinsg said in 1Timothy against women for example, Paul mentions women in high regard, even as leaders in the church and mentions some by name in his other letters.
