The Reformed Faith and Life ministry was a labor of love for Rev. Kayayan. His parents were born and raised in Eastern Turkey where most of his relatives perished during the genocide of Armenians by the Turks during WWI. His father, a missionary, and his mother fled to Greece, however, and survived and Rev. Kayayan was born and raised in Athens.

It was in 1992 (at the age of 64), that after retiring as the French language minister from the Back to God Hour, Rev. Kayayan turned toward his own people, the Armenians: he began a ministry of evangelization in his mother tongue called Christians for Armenia (Havadk Yev Guiank in Armenian).

In close association  with faithful and competent collaborators in Gyumri (the second largest city in the Republic of Armenia), and with the support of an interdenominational committee based in the U.S.A., many radio broadcasts and publications —in particular a quarterly magazine of high quality— were regularly produced.  In addition, he made several visits to this country dear to him (his first trip to Armenia was in 1993 at the age of 65, the last one took place in 2005, he was then 77). 

Until the age of eighty (in the beginning of the year 2008), and despite growing health problems, Rev. Kayayan worked relentlessly for the propagation of the Reformed faith in the land of his ancestors, accomplishing an important task acknowledged by Armenians from Armenia.  Rev. Kayayan passed away in May of 2008.

The ministry he started continues through the work of the North-American committee and the team in Armenia. The radio messages produced over a 16 year period continue to be aired in Armenia and Nagorno Karabagh, and the publications he had started are being finalized with the help of a team of scholars and editors in Armenia.
