This letter discusses the theme of Pope Francis' message for World Missionary Day, which is missionary communion and solidarity. It highlights the missionary vocation as a call to serve others through sharing and intercession. The letter invites the sisters to renew their commitment to the missionary mandate of "I entrust them to you" and to say "Here I am, send me!" in response to serving those still awaiting the proclamation of the Gospel, including young people, families in need, and whole populations. It encourages the sisters to contemplate the field the Lord has given them and to work with missionary enthusiasm.
