Between the arrival of the first Portuguese missionary in 1533, through the Dominicans and then the Jesuit missions of the 17th century, the politically inspired persecutions of the 19th century, and the Communist-led terrors of the twentieth, there have been many thousands of Catholics and other Christians murdered for their faith in Vietnam. Some were priests, some nuns or brothers, some lay people; some were foreign missionaries, but most were native Vietnamese killed by their own government and countrymen.
Record keeping being what it was, and because the government did not care to keep track of the people it murdered, we have no information on the vast bulk of the victims. In 1988, Pope John Paul II recognized over a hundred of them, including some whose Causes we do have, and in commemoration of those we do not. They are collectively known as the Martyrs of Vietnam (or Tonkin or Annam or the other older names of that country).
Propers for The Martyrs of Vietnam
Almighty and Everlasting God, who didst enkindle the flame of thy love in the heart of thy holy martyrs of Vietnam : Grant to us, thy humble servants, a like faith and power of love, that we who rejoice in their triumph may profit by their example; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost, one God, for ever and ever. Amen.
