Guille and Debbie Mac Kenzie were born and raised in Buenos Aires, Argentina. Guille studied his first theological degrees in Buenos Aires, was ordained at the age of 24 and served for six years. In December 2008, they moved to St. Louis, MO, to complete a Master of Theology and a Doctor of Ministry at Covenant Theological Seminary.

After studying in the States, the Mac Kenzie family returned to Argentina. Guille is serving as pastor of a multicultural church called "Iglesia Presbiteriana Nuevo Avivamiento," serving at a church planting movement called Mision Beta under the umbrella of City to City, and is involved in various theological education initiatives.

God has blessed Guille and Debbie with the joy of having three kids: Camila (14), Catalina (12) and Benjamin (9).

"Nuevo Avivamiento"

"Nuevo Avivamiento" (New Revival) is a multicultural community with a strong desire to share our faith in God. We enjoy diversity having many nations represented with people coming from places as diverse as Taiwan (mostly), Ecuador, the Philippines, South Korea, Venezuela, among others!

Misión BETA (Church Planting Movement)

Besides serving as pastor of the Spanish congregation at Nuevo Avivamiento church, Guille and other pastors in Argentina have launched a Church Planting Movement called Misión BETA. The purpose of Misión BETA is to glorify God and promote the expansion of his kingdom through the multiplication of Christian churches and the transformation of cities. This goal will be taken into practice in four ways:

  1. Promoting a permanent think-tank to reflect about the need to plant and revitalize churches towards the expansion of the kingdom of God and the transformation of society.
  2. Equipping pastors and leaders with an interest in church planting. We develop cohorts of church planters and leaders who meet bi-weekly.
  3. Sending and mentoring pastors and leaders with a call for church planting or revitalization. We are not yet involved in financial support ourselves, but come alongside church planters and pastors and help them raise their own support through different partners.
  4. Providing advice to churches that desire to assess their church searching opportunities for their own development or for planting a new church.

We invite you to request and read the information package for Misión BETA including more details and ways in which you can be a partner.

Description of our City

Buenos Aires is a globalized city of around 4 millions inhabitants, reaching 13 millions including the Great Buenos Aires suburban area. It is a very multicultural city that includes people from all continents. It is mostly Roman Catholic, although skepticism and indifference to faith and church are significantly increasing, especially in the context of the city. It also has one of the largest concentrations of Jewish and Muslim communities in South American countries.

We strongly believe that both Nuevo Avivamiento Church and Misión BETA can make a great kingdom impact in this important city that spreads its influence towards all Argentina.

Financial and Prayer Support Team

We believe it is important for us not to be fully dependent on external financial resources. Nuevo Avivamiento church has been supporting our part-time position for many years now. But we value your support to be able to spend more time in our church planting ministry and theological edition. Also, we are thankful to those who can help us afford Guille's Ph. D. studies, that will allow him to be better equipped to have a kingdom impact among the academic secular world.

We also value and appreciate our praying partners. If you would like to pray for us, please ask us to include your email address in our emailing list to receive our quarterly prayer bulletin. You may subscribe to the newsletter at
