The Vatican is less a physical setting than a remote center of authority in the novel: a place Alessandro dell’Aqua longs to return to, and the source of orders that can redirect priests and reshape the balance of religious power in Japan. Its reach is felt through messengers, trade routes, and disputes over obedience, where ecclesiastical command is inseparable from European competition for influence.

A Distant Home

For Alessandro dell’Aqua, the Vatican is bound up with home and the prospect of release from Japan. Praying in the earthquake-damaged chapel, he asks the Madonna to let him go home soon, naming both home and the Vatican as places from which he has been absent too long. His prayer contrasts the life he imagines in Italy with the burdens of his mission: Japanese politics, conflict, and the effort to keep the Church alive. The Vatican thus stands not only for institutional duty but for a distant life to which he hopes to return.

That longing gives the location a personal dimension absent from its formal decrees. Dell’Aqua’s exhaustion does not erase his commitment; he asks for strength and protection for the Church, while fearing that Spanish bishops who do not understand Japan will destroy what the Jesuits have begun. The Vatican is therefore both a desired destination and the center from which competing policies may imperil the work he has served.

Papal Authority and Missionary Routes

The Vatican’s institutional reach becomes concrete through a Papal Order delivered to Japan by special messenger from Macao. Issued with the formal agreement of the King of Spain, it requires priests of every religious order to travel to Japan by way of Lisbon, Goa, and Macao. It forbids travel directly from Manila on pain of immediate excommunication and orders all non-Jesuit priests to leave Japan for Manila, where they may return only by the prescribed route if their superiors permit it.

The order makes religious obedience a matter of geography. Access to Japan is channelled through a controlled sequence of ports, while the distinction between Jesuits and other orders determines who may remain. The threat of excommunication gives the decree spiritual force; its routing rules also bear directly on the movement and presence of European religious personnel. A distant authority can therefore intervene in Japan without appearing there, by controlling the routes through which its clergy arrive and the conditions under which they stay.

Contested Control

The Papal Order is received amid a struggle over whether Portuguese and Jesuit influence in Japan will endure. Friar Perez rejects the order at first, insisting that the territory is Portuguese and the province belongs to his side. His challenge is answered with the claim that the situation has changed: the King of Spain has overthrown the Jesuit General in Rome, and a Spanish bishop, viceroy, and captain of the Black Ship are expected. The exchange presents the Vatican not as a neutral abstraction but as a contested source of jurisdiction, entangled with the transfer of political and commercial power.

The order also gives institutional form to a division already visible in Japan. The Portuguese and their priests have become essential intermediaries in trade: Jesuits who learn Chinese and Japanese negotiate and interpret, helping sustain commerce that carries Chinese silk and Japanese silver. Because that exchange touches the lives of samurai, Japanese rulers tolerate the priests and the spread of their religion. Against this dependence, the Vatican’s instructions attempt to regulate which clergy may enter and remain, while the Spanish intervention threatens the established Portuguese-Jesuit arrangement.

Significance

The Vatican’s role links local religious authority to an international network of trade, travel, and imperial rivalry. Its orders can determine who reaches Japan, while the power struggle around Rome threatens to alter the institutions that make European trade there possible. For dell’Aqua, that reach is at once a source of duty and a prospect of homecoming; for the Church in Japan, it is a force capable of preserving or disrupting a fragile presence.
