The book of the Correspondence, the collected letters addressed by Marcel Van to his friends and family, is the third volume in the series of the Complete Works of Marcel Van. Marcel Van speaks of his spiritual life to his spiritual director, Father Antonio Boucher. He encourages and guides his little sister Tê in the discernment of her religious vocation. He also writes to his parents and to the many friends he had throughout his life. Thus we enter into his close relationships and discover through these readings the complete dedication, faith, strength and courage which he possessed in both moments of joy and trials. The plain and straightforward character of these letters enables us to better get to know this young Vietnamese brother.
