Why does Iglesia ni Cristo use the Lamsa Bible? Recently, I met members of a group called Iglesia ni Cristo (Tagalog for "Church of Christ"). After I looked them up and watched some debates between them and other Christian churches, I observed that while English speakers in their group support their teachings using a number of Bible translations, the Lamsa Bible seems to be the one they most often reference.

What are the main reasons Iglesia ni Cristo uses the Lamsa Bible and how is this translation viewed by "mainstream" scholars with a traditional approach to biblical scholarship?
Iglesia ni Cristo (English: Church of Christ; abbreviated as INC) is an international Christian denomination religion that originated in the Philippines. It was registered and preached in 1914 by Felix Manalo,who became the first executive minister [1].

This new sect Iglesia Ni Cristo ( English: Church of Christ) is just 100 years old.They are avid Unitarians.Their Unitarian Theology is identical to Socinus than to Arius. 

The Lamsa Bible is an English translation of the Aramaic Bible by George Lamsa [2].

The main reasons INC uses the Lamsa Bible is because it suits their theology. 

The Lamsa Bible contains the exact phrase "church of Christ" in Acts 20:28 whereas all Greek MSS reads " ekklessia theou."

INC strictly teaches its doctrines in terminology that is found only in the Bible. 

They use Acts 20:28 twofold purpose: 

1) To deny the divinity of Christ [ it wasn't God's blood].

2) To affirm their claim that the name of the only true church is church of Christ.[For INC other churches whose name is not church of Christ is automatically a false church].
