ISB ~ Mark 16 v15 - 16
Mark’s account of the Great Commission stresses that the apostles must spread the Christian faith by (1) evangelization (preach) and (2) the administration of the sacraments (baptized; CCC 977, 1253, 1257). The apostles’ mission to the whole creation includes all the nations of the world (Lk 24:47). See note on Mt 28:19.
