Do you know this man? Perhaps not! He is the sole DESIGNER of Iglesia ni Cristo® chapels we find all around the Philippines.
His name is CARLOS A. SANTOS-VIOLA, a devout Catholic! Says Wikipedia:
"Carlos was a lifelong devout Roman Catholic. He ministered for the Our Lady of Lourdes Church in Quezon City and was frequently invited to join the INC but repeatedly denied the invitations due to ideological differences. He also taught architecture at the college where he graduated, and helped found the Philippine Institute of Architects in 1938."
