San Marcos Church was established in 1994 as a church plant of the Presbyterian Church in America to reach the English speaking community in Eastern Santiago by Jim and Portia Reimer and Sam and Lois Mateer.  San Marcos is small but it has a big heart and has sent Christians to many parts of the world.   Our desire is to grow larger by attracting the unchurched into a relationship with Jesus Christ by training Christians to serve the Lord, thereby sending them out as evangelists to introduce others to the love of our Lord and Savior.

We believe the Bible is the written word of God, inspired by the Holy Spirit and without error in the original manuscripts. The Bible is the revelation of God’s truth and is infallible and authoritative in all matters of faith and practice.

We believe in the Holy Trinity. There is one God, who exists eternally in three persons: the Father, the Son, and the Holy Spirit.

We believe that all are sinners and totally unable to save themselves from God’s displeasure, except by His mercy.

We believe that salvation is by God alone as He sovereignly chooses those He will save. We believe His choice is based on His grace, not on any human individual merit, or foreseen faith.

We believe that Jesus Christ is the eternal Son of God, who through His perfect life and sacrificial death atoned for the sins of all who will trust in Him, alone, for salvation.

We believe that God is gracious and faithful to His people not simply as individuals but as families in successive generations according to His Covenant promises.

We believe that the Holy Spirit indwells God’s people and gives them the strength and wisdom to trust Christ and follow Him.

We believe that Jesus will return, bodily and visibly, to judge all mankind and to receive His people to Himself.

We believe that all aspects of our lives are to be lived to the glory of God under the Lordship of Jesus Christ.
