About Cathy and Juan’s ministry
From their home base in Manila, Philippines, Cathy Chang and Juan Lopez help global partners address issues of migration and human trafficking. The UN’s International Labor Organization estimates 21 million people are victims of coerced labor and/or forced sexual exploitation. While human trafficking is a worldwide problem, countries in Asia are increasingly vulnerable. Cathy and Juan will work with Asian churches and non-governmental organizations to help coordinate efforts related to the scourge of modern-day slavery. They will also resource various programs of the Presbyterian Mission Agency and U.S. congregations concerned about the issue.

Country context
Almost two-thirds of the world’s inhabitants are clustered in Asia and the surrounding Pacific region. While Christianity is the faith of a small minority of people in this vast area, the church is growing in places like China, Korea, the Philippines, Taiwan, and Vietnam. In recent years, much of the region has experienced economic expansion, but many Asians have not shared in this prosperity. The Presbyterian Church (U.S.A.) joins with Asian partners as they proclaim Christ’s good news and confront issues such as climate change, food security, health care, education and human trafficking.

About Cathy and Juan

Cathy and Juan focus their vision on people whose dreams have been denied.

They carry a deep concern for those whose hopes for a better life for themselves and their families have been dashed by human traffickers. “I pray the Lord would lead and guide us as we address migration and human trafficking by participating in God’s work to redeem economic systems of exploitation and exchange them for life-giving opportunities and education, while tending to the healing of peoples’ bodies and spirits,” Cathy says.

Cathy and Juan discovered each other and their enduring passion for mission in 2002 while serving in Egypt as young adults. Cathy was working with the PC(USA)’s Young Adult Volunteer (YAV) program, and Juan was serving with Chrétienne en Orient (Christians in Action in the East), a mission agency supported by French Protestants.

“In Egypt, we started dating and dreamed about the possibilities of serving in mission together,” Cathy says. A long engagement ensued, with Cathy returning to the United States and eventually attending seminary, and Juan returning to France to begin a career in social work.

They married in 2008 while Cathy was a pastoral resident at Bryn Mawr Presbyterian Church in Pennsylvania. In 2009, Cathy became associate pastor of Memorial Presbyterian Church in Midland, Michigan. In Michigan, Juan resumed his social work career, serving as a site supervisor for Big Brothers Big Sisters of the Great Lakes Bay Region. Yet their call to international mission persisted.

“When we discovered this new position in Presbyterian World Mission, we sensed God was providing an answer to our prayers and search,” Juan says.

Juan and Cathy bring to mission service deep experience in bridging cultures. Cathy grew up in New Jersey and Pennsylvania in the home of Korean immigrant parents. Juan was born in Chile, but his family moved to France when he was a child.

Forced migration, a reality experienced by many victimized by human trafficking, is found in the family histories of both Cathy and Juan. Several of Cathy’s relatives fled North Korea for South Korea and later came to the United States. Juan’s family’s move to France stemmed from his father’s opposition to the Chilean government. France accepted Juan’s father as a political refugee.

The couple is inspired by Genesis 12:1-3, where God called Abram to go “to the land that I will show you.” They identify with Abram not because their families have experienced exile, internal displacement, and immigration. Instead, they look to God’s promise to Abram that all families of the earth would be blessed through him.

“Out of God’s desire to bless all the families of the earth, we also desire to serve as a channel of God’s blessings for many families of the earth,” Juan says.

Prior to entering the YAV program, Cathy was a consultant for Accenture, a multinational management consulting and technology company. She received a bachelor’s degree from Carnegie Mellon University in public policy and management and economics (double major) and a master’s degree from Carnegie Mellon in public policy and management. Her theological degree is from Princeton Seminary. She is a member of Lake Huron Presbytery.

In France, Juan was a social worker with Foyer de l’ Enfrance Charles Frey (Hearth of Youth Charles Frey) in Strasbourg. He holds a master’s degree in sociology from Marc Bloch University in Strasbourg, France. He is a member of Memorial Presbyterian Church in Midland, Michigan.

Cathy and Juan are the parents of a daughter, Aurélie Chang Lopez, who was born in 2012.
