While I cannot provide specific details about a meeting between Pope Leo XIV and U.S. Vice President JD Vance and Secretary of State Marco Rubio, I can offer information on the Holy See's approach to international relations and diplomacy.

The Holy See's Diplomatic Mission

• Listening and Cooperation: The Pope engages in attentive listening to understand the concerns and desires of government leaders and suggests sincere cooperation on issues affecting humanity 4.

Religious Freedom

• Fundamental Right: Religious freedom is considered a fundamental human right that reflects the highest human dignity and is essential for individuals to seek truth and fulfill their potential 6.
• Beyond Private Thought: Religious freedom extends beyond private thought and worship to living according to ethical principles derived from found truth, both privately and publicly 6.
• Protection and Guarantee: Legal systems are called upon to recognize, guarantee, and protect religious freedom as an intrinsic right inherent to human nature and a sign of a healthy democracy 6.
• Inherent Dignity: Religious liberty is rooted in the dignity of the human person and is a fundamental human right without geographical boundaries 7.
• No Coercion: Religious freedom implies immunity from coercion by individuals, social groups, or any human power, ensuring that no one is forced to act against their beliefs 7.
• Civil Right: Religious freedom is based on the dignity of the human person and must be sanctioned as a civil right in the legal order of society, concerning both individuals and communities 8.

The Holy See and the War in Ukraine
