“… taking every thought captive to the obedience of Christ” (2 Corinthians 10:5)

This is the website of Rev. Bill & Aletha Green. They have served the cause of Reformed missions in Costa Rica and Latin America for over 30 years in church planting, Christian school education, leadership training and publications.

The Protestant Reformation of the 16th century recovered the central biblical teachings of God’s sovereignty and grace in salvation, Christ’s lordship over the Church and the world, and the Holy Scripture’s role as infallible rule. We call this the “Reformed faith”, but it is our perspective that this is the same Gospel taught by the early Church, and indeed by the apostles. Our passion is to see people come to faith in a sovereign and merciful God, in whose Word we can have absolute confidence.

In some countries of Latin America, Reformed churches have a long history. In other countries the Reformed faith is virtually non-existent. In all cases, the historic faith of the Church is under attack, either by liberal tendencies which undermine Scripture’s authority, or more recently by the neo-pentecostal “health and wealth” message.

Rev. Bill & Aletha Green have labored in church planting in Costa Rica, and are currently involved in their third church plant on the north east side of San Jose, Costa Rica. They also helped establish the Tepeyac Christian grade school and high school which Aletha served as principal for over 15 years. And Bill is Executive Secretary for the “Latin American Fellowship of Reformed Churches” (CLIR) which has as its goal bringing Reformed churches and groups together throughout Latin America to strengthen church leaders, provide support for those who need it, and serve the propagation and defense of the Reformed faith. Toward that end, CLIR has established a publishing ministry, and is providing Latin America with solid, Reformed resources.

    My wife and I were just talking about Costa Rica and were wondering about moving there
    I was surprised to see that there is a Reformed church which has the 3 forms of unity
    explaining the essence of the Bible as their basis of faith. Absolutely wonderful how God
    continues his Church gathering work also in Costa Rica!!.

    I wish you a blessed Sunday.

    Besides English, what other language is spoken there?

    I will be looking at information about Costa Rica
