The death of Mr. Thomas Sumantri on 30 May 2017 in Singapore was announced in the SSPX Asia magazine's August 2017 issue.
Here is the announcement:
"Mr Thomas Sumantri passed away on Tuesday 30 May 2017; he had received the last rites and viaticum. He was the biggest benefactor of the Society in Asia. It is thanks to his generosity that the apostolate in Southeast Asia was started as he used to pay for all the airplane tickets of the priests who would fly from Australia in the late 1980s/early 1990s to serve Hong Kong, the Philippines, Sri Lanka, Singapore.
When he moved to Singapore from Hong Kong with his family in the early 90s, he hosted the Mass in his home and when a proper chapel was established, he continued to show himself a generous supporter helping also with the setting up of the priory in the year 1999".
