Our position is that Christians should not and would not defraud one another purposefully in any manner. This includes the unauthorized use of the Art of Cha Yun Do and the unauthorized use of the name Christian Martial Arts Fellowship. We rely on the Bible as the qualifier in this area, 1st Corinthians 6:7-11 and 1st Thessalonians 4:6-8 being primary examples

If there is any question as to the authenticity of the school or instructors or their having authorization to use the Art of Cha Yun-do or the name Christian Martial Arts Fellowship, we suggest, before making any agreements or enrolling, you ask to see their signed and stamped "Certificate of Affiliation." Each Chief Instructor receives one for each school, each year. The certificate is only valid for one year.

If they do not have the proper certificate, they are not approved to use Cha Yun-do in any fashion nor the name Christian Martial Arts Fellowship.
