Ministry in Mexico

From 2003 to 2011, we were teaching in Pachuca, Mexico, at the Centro de Estudios Teológicos y Ministeriales, training pastors, missionaries and other Christian workers for the ministry in Mexico and other countries. The apostle Paul talks about this type of ministry in 2 Timothy 2:2. Dean taught Synopsis of the Old and New Testaments, Introduction to Biblical Hebrew, a Bible course on Isaiah, and a theology course on Soteriology (the doctrine of salvation). He co-pastored a mission church with the Seminary director where he taught a series on Second Peter, the doctrine of salvation, a series on the Christian life, and a series of studies on the book of Revelation. Sylvia taught individual music classes to students in piano, voice, flute and autoharp at the seminary.

Live seminary classes online

After an eight-year seminary ministry in Mexico, in 2011 we had to leave because of the effects on Sylvia of the elevation in Pachuca (8,000+ feet). But God in His marvelous grace enabled us to continue with teaching online for the same seminary. Dean is still considered a professor at the Center for Theological and Ministerial Studies in Pachuca, Mexico (CETYM). There is not a huge pool of trained pastors and theologians who would be able to serve as seminary faculty and so it is difficult to find teachers in Mexico. Dean teaches Introduction to Biblical Hebrew, Synopsis of the Old and New Testaments, Isaiah, the Doctrine of Salvation, Summary of Doctrine, and Analysis of Romans. These are live classes by videoconferencing and are the equivalent of regular seminary classes. The students come to class just like they do for other professors who are on site. In addition we are able to accomodate some remote students who are not able to attend classes at the seminary in Pachuca. Sylvia assists with administration, communication with former students, and other support activities. We rejoice to see our students going into the pastorate, cross-cultural missions in other countries, and support work in churches (as in 2 Tim. 2:2). Several of our former students have served in countries closed to the gospel and one of them has seen several people come to know Christ. Two of these have not been able to return to their fields since the pandemic of Covid-19. We pray that soon that will be resolved, but God has His plans.

Dean has been able to visit the seminary for a couple of weeks at the beginning of the first semester several times in recent years. These visits enable him to get to know the new students. It makes it easier to have an online relationship with the students when he has spent time with them face-to-face. These visits were not been advisable during the pandemic.


We would covet your prayers in these areas:

  • Continued good connection and class participation
  • More students and faculty for the seminary in Pachuca
  • The financial support to continue (it is a faith ministry)
  • The health and strength for both of us to continue in this ministry
