Paul supposedly evangelized Spain. In the 1st - 2nd centuries AD, brief mention is made of Spanish Christians. In the 3rd century AD, Christian communities in Spain emerge into the historical record, "scattered" across Spain (in the Roman provinces of Tarraconensis & Baetica). Plausibly, after being freed from Rome circa 62 AD (about when Josephus helped free Jewish High Priests, as if Nero granted clemency "to all those Jews" at the same time), Paul sailed to Spain, and travelled to-and-fro, on Roman roads there, much as he had done in Asia & Greece. (There may have been an ancient Jewish presence in Tartessos, plausibly Biblical Tarshish.)
Afterwards, Paul's "Pastoral" epistles place him in Crete, Ephesus, Macedonia, Greece & Rome, circa 64-65 AD. "Connecting the dots", Paul plausibly sailed from Spain, to Carthage, and Cyrene, in Africa; and then to Crete and the Greek world; before being arrested to Rome. The first Bishop of Carthage was the first Christian convert, of Paul's preaching, in Greece -- perhaps Paul called Epaenetus, from Rome (Rom 16), to Carthage, circa 64 AD, before returning, through Crete, to Ephesus, and Greece, trying to deal with heresies.
