It was significant, but hardly surprising, that, after his illness, Manning should have chosen to recuperate in Rome. He spent several months there, and his Diary during the whole of that period is concerned entirely with detailed descriptions of churches, ceremonies, and relics, and with minute accounts of conversations with priests and nuns. There is not a single reference either to the objects of art or to the antiquities of the place; but another omission was still more remarkable. Manning had a long interview with Pius IX., and his only record of it is contained in the bald statement: "Audience to-day at the Vatican." Precisely what passed on that occasion never transpired; all that is known is that His Holiness expressed considerable surprise on learning from the Archdeacon that the chalice was used in the Anglican Church in the administration of Communion. "What!" he exclaimed, "is the same chalice made use of by every one?" "I remember the pain I felt," said Manning, long afterwards, "at seeing how unknown we were to the Vicar of Jesus Christ. It made me feel our isolation."
On his return to England, he took up once more the work in his Archdeaconry with what appetite he might. Ravaged by doubt, distracted by speculation, he yet managed to maintain an outward presence of unshaken calm. His only confidant was Robert Wilberforce, to whom, for the next two years, he poured forth in a series of letters, headed "Under the Seal" to indicate that they contained the secrets of the confessional, the whole history of his spiritual perturbations. The irony of his position was singular; for during the whole of this time Manning was himself holding back from the Church of Rome a host of hesitating penitents by means of arguments which he was at the very moment denouncing as fallacious to his own confessor. But what else could he do? When he received, for instance, a letter such as the following from an agitated lady, what was he to say?
