An example of "ecumenism of blood"

It all began with the case of the missing pastor.
On the morning of 13 February, Raymond Koh was exiting a highway in the leafy suburb of Kelana Jaya just outside of the Malaysian capital, Kuala Lumpur.
A widely circulated CCTV clip appears to show what happened next. A convoy of black SUVs and motorcycles is seen swooping down on his car and boxing it in by the side of the road.
Then, several men jump out and run to Mr Koh. There is a flurry of activity, and the convoy moves off - along with his car. It is allegedly the last time anyone sees him.
...
The heads of Malaysia's Methodist, Anglican and Roman Catholic churches attended a prayer service for Mr Koh last week.
