If you are interested in a short, free, English-language resource for learning about Marcel Văn, I can recommend this interview with Gilles Berceville OP: Saint Thérèse’s Spiritual Little Brother.

Here is a quote from the interview about Marcel’s view of our loving God:

God is “condescending”: He is not a God that one would think punishes us with rigor, demanding what we cannot do, but a God who thinks how to help us, and in a certain way adapts himself to what we are so that we will adapt ourselves to what he is.

And a somewhat longer reflection on Little Văn’s place in this Church which is Catholic:

Universality isn’t an abstract ideal. In love, there is concrete enrichment of all for all. This is to an extent what Van enables us to experience. He makes us discover, thanks to the Gospel, what should be the meeting between East and West.

His message is very timely. For the first time, we discover a Christian of the Far East who lived his faith intensely, whose message is original and of such magnitude that a French theologian like me begins to study Vietnamese to learn something more of the Gospel…

With Van, the East again says something of the Gospel to the West. It is a magnificent example of exchange between two Churches.

But those are some quotes. The interview as a whole is helpful and good. Gilles Berceville is the author of some works about Marcel.
