Filipino Catholics will wear red on Nov. 22, to show solidarity with persecuted Christians around the world.

The campaign called Red Wednesday will be launched in the country by the Aid to the Church in Need, a global Catholic group that supports Christian communities suffering from persecution.

The event aims to create awareness among Filipinos about the severity of Christian persecution around the world.

The Philippines will join Christians in the United Kingdom where Red Wednesday was first held last year. The global campaign will also be held in Malta, Italy, and Brazil.

A total of 45 cathedrals, 24 shrines, and five basilicas in the Philippines are participating in this year’s activities by illuminating the facade of churches in red.

"Red is the color of martyrdom in the Christian faith," read the group's statement.

"The Red Wednesday campaign will shine a light on religious persecution and will honor all Christians who have suffered and died for Christ," added the statement.

The group noted that Filipinos seemed to have developed a "blind spot" about the nature and scale of Christian persecution around the world.

"Given that our country is predominantly Christian, Filipinos find it difficult to grasp a reality where Christians can be persecuted," said the group, adding that many are not even aware of the challenges being encountered by Christians in the southern part of the country.

"Let Red Wednesday be the start for Filipinos to lend their voice to the global call to uphold religious freedom and advocate for inter-faith harmony," added the statement.

A study by the Center for Studies on New Religions in 2016 found that over 90,000 Christians were murdered last year. It is equivalent to one Christian being killed for the faith every six minutes.

The study also revealed that half a billion Christians were unable to freely express their faith, affirming the declaration of Pope Francis that there are more Christians suffering today than there were in the early years of Christianity.
