Here is an older post from 2014. Some background of these saints from another post is here
One of the things that is so memorable about Andrew Dung-Lac is that he was born a poor pagan Vietnamese. His catechesis was coupled with food and shelter, and then baptism. He was not born into Christianity, and the country he lived in was not historically Christian, and he was ethnically Vietnamese. Why do these points interest me? To start, Andrew became a priest, and taught catechism. That was a step up from the impoverished life he was born into, but does not begin to explain this person’s character. Andrews’s character and spirituality come out after the first time he went through imprisonment and persecution for his Christian faith. That persecution was under the emperor’s directive, and was wide spread; though Andrew was able at first to gain freedom with the support of his congregation. This is the part where this priest’s character and spirituality are revealed. After that persecution the priest changed his name, modified his location, and continued his mission. After imprisonment, how easy would it have been for him to simply remove his collar and blend in amongst his countrymen? He was ethnically Vietnamese, so blending in would have been easy. The persecutions going on in that country were among the most brutal in history, yet he did not remove his clerical collar, and to me that speaks volumes about the extent the Holy Spirit descended onto that priest. At his baptism he was initiated into the faith with water, at his first persecution was proof positive that he had received that Spirit. As he continued preaching and baptizing people into the faith, those persecutions continued and they were directed at Christians with unspeakable brutality. Andrew continued with his mission until he was beheaded for the faith at the age of forty-four. His story contains examples of the three types of baptism, that one of water, of the spirit, and by blood. The brutality towards Christians in that country at that time were horrendous. Andrews’s story is easy to tell because it is a brief biographical sketch of a single person. There were one hundred and seventeen martyrs, and each had their own unique story, though I am certain they all had that desire to live and die for their faith and preach the gospel of Christ. It was that faith that defined them, not their ethnicity or social standing. They were European and Vietnamese, Priests, Religious, and Lay people: all placing their faith in Christ. Their story of faith is remarkable and unforgettable.
