The congregation was born not knowing exactly what lay ahead. In September 1863, the first group of missionaries set forth for Inner Mongolia. In the winter of 1865, Verbist and his four companions arrived in inner Mongolia, which was entrusted to the fledgling congregation by Rome, and where they immediately began organizing small Christian communities. The founding Fathers never imagined that many would follow their footsteps notwithstanding the cost of traveling by sea and in the hinterlands of China. Three years later on February 23, 1868, Verbist died of typhoid fever at the age of 45 in Lao-Hu-Kou.
