From time to time, depending on the topic of study, fellowships may invite an outside speaker to elaborate further on the theme or discuss a related issue. During the year FCCW fellowship groups studied "Spiritual Gifts," the fellowship at St. Catherine's of Alexandria in Riverside invited the Spiritual Gifts team to speak to the group. Four members of the team spoke on the "Gifts of the Holy Spirit" and enlightened fellowship members about the purpose of the charisms and how they are used.
During the year FCCW fellowship groups studied "Holiness," one fellowship invited a local university professor who role-played Dorothy Day. After her presentation, the members asked questions and learned more about this contemporary woman in the church.
