Jesus therefore called to Him the Twelve, and began to send them forth. In so doing, His directions revealed at once His wisdom and His fears for them.
Not even for unfallen man was it good to be alone. It was a bitter ingredient in the cup which Christ Himself drank, that His followers should be scattered to their own and leave Him alone. And it was at the last extremity, when he could no longer forbear, that St. Paul thought it good to be at Athens alone. Jesus therefore would not send His inexperienced heralds forth for the first time except by two and two, that each might sustain the courage and wisdom of his comrade. And His example was not forgotten. Peter and John together visited the converts in Samaria. And when Paul and Barnabas, whose first journey was together, could no longer agree, each of them took a new comrade and departed. Perhaps our modern missionaries lose more in energy than is gained in area by neglecting so humane a precedent, and forfeiting the special presence vouchsafed to the common worship of two or three.
St. Mark has not recorded the mission of the seventy evangelists, but this narrative is clearly coloured by his knowledge of that event. Thus He does not mention the gift of miraculous power, which was common to both, but He does tell of the authority over unclean spirits, which was explicitly given to the Twelve, and which the Seventy, returning with joy, related that they also had successfully dared to claim. In conferring such power upon His disciples, Jesus took the first step towards that marvellous identification of Himself and His mastery over evil, with all His followers, that giving of His presence to their assemblies, His honour to their keeping, His victory to their experience, and His lifeblood to their veins, which makes Him the second Adam, represented in all the newborn race, and which finds its most vivid and blessed expression in the sacrament where His flesh is meat indeed and His blood is drink indeed. Now first He is seen to commit His powers and His honour into mortal hands.
In doing this, He impressed on them the fact that they were not sent at first upon a toilsome and protracted journey. Their personal connection with Him was not broken but suspended for a little while. Hereafter, they would need to prepare for hardship, and he that had two coats should take them. It was not so now: sandals would suffice their feet; they should carry no wallet; only a staff was needed for their brief excursion through a hospitable land. But hospitality itself would have its dangers for them, and when warmly received they might be tempted to be fêted by various hosts, enjoying the first enthusiastic welcome of each, and refusing to share afterwards the homely domestic life which would succeed. Yet it was when they ceased to be strangers that their influence would really be strongest; and so there was good reason, both for the sake of the family they might win, and for themselves who should not become self-indulgent, why they should not go from house to house.
