"It also emphasizes our need for the totality of her help, while recognizing that FOCUS as an apostolate is especially in need of particular graces," he added.
Martin sees Our Lady of Fatima as representing a focus on a missionary's interior life, while Our Lady of Guadalupe represents a focus on the exterior life.
"Both are directed toward the same end: the salvation of souls through the fulfillment of the Great Commission to know Jesus Christ and make disciples of all nations," he said.
He cited Our Lady of Fatima's request to pray, especially the rosary and devotions to the Sacred Heart, as well as her encouragement to make sacrifices for souls. He said devotion to Our Lady of Guadalupe is an opportunity to pray for spiritual fruitfulness, given her precedent of inspiring the conversion of 10 million people.
Martin said he has a particular devotion to Our Lady of Fatima, saying she "played an instrumental role in breathing new life into my dead faith."
He said FOCUS reaches out to students "at a pivotal time in their lives" when they face the pressures of contemporary campus life.
"We share the gospel of Christ's love, the truth of the Catholic faith and our very selves to help reach the world for Christ through our families, vocations and parishes," he said.
