Where we found brethren. — The fact is significant as showing, in the absence of any distinct record, the extent to which the new society had been silently spreading. Who had been the agents in preaching the gospel there we can only conjecture, but a city which was en rapport, like Puteoli, with both Alexandria and Rome, may have received it from either. One or two coincidences, however, tend to the former rather than the latter conclusion. We find in Hebrews 10:24 a salutation sent from “those of (or, better, from) Italy.” This would not be a natural way of speaking of Christians of Rome, and we are led, therefore, to think of some other Italian Church. The only such Church, however, of which we read in the New Testament is this of Puteoli, and we naturally infer that the writer of that Epistle refers to it. But the writer was, in the judgment of many critics (see Introduction to the Epistle to the Hebrews), none other than Apollos, the eloquent Alexandrian Jew of Acts 18:24, and some have been led to think that it was addressed to the Hebrew disciples of the Therapeutæ, or ascetic, class, in the Delta of the Nile. All these facts tend to the conclusion that there was a connection of some kind between Alexandria and some Italian Church, and the theory that that Church was at Puteoli, though not proven, at least combines and explains all the phenomena. We find from Josephus (Ant. xvii. 12, § 1) that there was a considerable Jewish element in the population of Puteoli. They had, indeed, spread themselves through the greater part of Italy, and the remains of a Jewish cemetery have been found even near Perugia.
Were desired to tarry with them seven days. — As before at Troas (Acts 20:6) and Tyre (Acts 21:4), so here, we can scarcely fail to connect the duration of St. Paul’s stay at Puteoli with the wish of the Church there, that he should be with them on one, or, it may be, two Sundays, that so he might break bread with them, and that they might profit by his teaching. The kindness of the centurion is seen once more in the permission which made compliance with the request possible.
And so we went toward Rome. — The journey would lead them through Cumæ and Liternum to Sinuessa, a distance of thirty-three miles from Puteoli. Here they would come upon the great Appian Road, which ran from Rome to Brundusium, the modern Brindisi. The stages from Sinuessa would probably be Minturnæ, Formiæ, Fundi, and Terracina, making altogether a distance of fifty-seven miles. At this point they would have to choose between two modes of travel, taking the circuitous road round the Pontine Marshes, or going by the more direct line of the canal. Both routes met at Appii Forum, eighteen miles from Terracina. For us well-nigh every stage of the journey is connected with some historical or legendary fact in classical antiquity. We think of the great Appius Claudius, the censor from whom the Via and the Forum took their names; of the passage in the over-crowded canal track-boat, with its brawling sailors, and of the scoundrel inn-keepers, whom Horace has immortalised in the narrative of his journey to Brundusium (Sat. i. 5). All this was, we may believe, for the Apostle as though it had not been. Past associations and the incidents of travel, all were for him swallowed up in the thought that he was now on the point of reaching, after long delays, the goal after which he had been striving for so many years (Acts 19:21; Romans 15:23).
