Many churches have various missions (sometimes called societies) within their structure that are set in place to reach out in various ways. Some are to share the word, some to help the elderly, the infirm, and others are to help those in financial need. Missions don't have to involve travel to foreign lands. There are plenty of people everywhere with different types of needs. What missions of the Catholic Church are you familiar with? Have you ever participated in these missions, whether as a volunteer, organizer, recipient, etc.?
One I've encountered is the Society of St. Vincent de Paul. It's an organization within the Catholic Church that provides outreach to those in need, whether the need be food, financial assistance, furniture, toiletries, etc. I've been on both the giving and receiving ends of their mission, and I think they do a good job, and make a positive difference in the lives of many people. Here's a link to their website, in case anyone would like to learn more. https://www.svdpusa.org/
