Demonstratio Evangelica (The Proof of the Gospel) Book 3
1. 3:6 With one word and voice He said to His disciples: "Go, and make disciples of all the nations in My Name, teaching them to observe all things whatsoever I have commanded you." And He joined the effect to His Word;
2. 3:7 Whereas He, who conceived nothing human or mortal, see how truly He speaks with the voice of God, saying in these very words to those disciples of His, the poorest of the poor: "Go forth, and make disciples of all the nations." "But how," the disciples might reasonably have answered the Master,...But while the disciples of Jesus were most likely either saying thus, or thinking thus, the Master solved their difficulties, by the addition of one phrase, saying they should triumph "In MY NAME."
3. 3:7 For He did not bid them simply and indefinitely make disciples of all nations, but with the necessary addition of "In My Name." And the power of His Name being so great, that the apostle says: "God has given him a name which is above every name, that in the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth,"
4. 3:7 He shewed the virtue of the power in His Name concealed from the crowd when He said to His disciples: "Go, and make disciples of all nations in My Name." He also most accurately forecasts the future when He says: "For this gospel must first be preached to all the world, for a witness to all nations."
These words were said in a corner of the earth then, and only those present heard it. How, I ask, did they credit them, unless from other divine works that He had done they had experienced the truth in His words? Not one of them disobeyed His command: but in obedience to His Will according to their orders they began to make disciples of every race of men, going from their own country to all races, and in a short time it was possible to see His words realized.
5. 3:7 I am irresistibly forced to retrace my steps, and search for their cause, and to confess that they could only have succeeded in their daring venture, by a power more divine, and more strong than man's, and by the co-operation of Him Who said to them: "Make disciples of all the nations in My Name."…You yourself will recognize what power their word has had, for the Book of the Acts agrees with their having these powers, and gives consistent evidence, where these men are reported by their power of working miracles by the Name of Jesus to have astonished the spectators present.
Demonstratio Evangelica (The Proof of the Gospel) Book 9
6. 9:11 And He says to them, "The kingdom of God shall be taken away from you, and shall be given to a nation bearing the fruits of it." And He bids His own disciples after their rejection, "Go ye and make disciples of all nations in My Name.''
Theophania Book 4
7. 4:16 Our Saviour said to them therefore, after His resurrection, "Go ye and make Disciples of all nations in My Name,"
Theophania Book 5
8. 5:17 But, if one so dared; still he brought not the matter to effect. He (the Saviour) said in one word and enouncement to His Disciples, "Go and make disciples of all nations in My Name, and teach ye them every thing that I have commanded you."
9. 5:46 He again put forth the word of God in the precept, which He gave to these His powerless Disciples, (viz.) "Go ye and make Disciples of all nations!" It is likely too, His Disciples would thus address their Lord, by way of answer: How can we do this ?…And, What power have we upon which to trust, that we shall succeed in this enterprise? These things therefore, the Disciples of our Saviour would either have thought, or said. But He who was their Lord solved, by one additional word, the aggregate of the things of which they doubted, (and) pledged them by saying, “Ye shall conquer in My Name.”
10. 5:46 For it was not that He commanded them, simply and indiscriminately, to go and make Disciples of all nations; but with this excellent addition which He delivered, (viz): "In My Name." Since it was by the power of His Name that all this came to pass; as the Apostle has said, "God has given Him a name, which is superior to every name: that, at the name of Jesus, every knee should bow which is in heaven, and which is in earth, and which is beneath the earth."
11. 5:49 I am again compelled to recur to the question of (its) cause, and to confess, that they (the Disciples) could not otherwise have undertaken this enterprise, than by a Divine power which exceeds that of man, and by the assistance of Him who said to them, "Go, and make Disciples of all nations in My Name."
Church History Book 3
12. 5:2 But the rest of the apostles, who had been incessantly plotted against with a view to their destruction, and had been driven out of the land of Judea, went unto all nations to preach the Gospel, relying upon the power of Christ, who had said to them, “Go ye and make disciples of all the nations in My Name.”
The Oration of Eusebius in Praise of Emperor Constantine Ch. 16
13. 16:8 Surely none save our only Saviour has done this, when, after his victory over death, he spoke the word to his followers, and fulfilled it by the event, saying to them, “Go, and make disciples of all nations in My Name.” He it was who gave the distinct assurance, that his gospel must be preached in all the world for a testimony to all nations, and immediately verified his word: for within a little time the world itself was filled with his doctrine.

Psalms 65:5-6 "Hence we should rejoice in him, who by his power endureth forever. We should understand these words of that saying of Christ: 'All power is given to me in heaven and on earth. Going make disciples of all the nations in My Name.'"

Psalms 67:34 "That Christ's voice was endowed with power is evident from his, deeds; for when he said to his disciples: 'Come, follow me, and I shall make you fishers of men," he actually fulfilled this promise by his power; and again when he commanded them saying: 'Going make disciples of all the nations in My Name,' he manifested his power in very deed."

Psalms 76:20 "From the preceding verse we learn that the earth shook and trembled. This was realized when Christ entered Jerusalem, and the entire city was in consternation; also when the nations of the world trembled upon hearing the words of the Gospel from the lips of the Apostles. How should we understand the prophet when he says that Christ's way is in the sea, and his paths in many waters, and his footsteps will not be known? This passage receives light from his promise to his disciples: 'Going make disciples of all nations in My Name,' and, 'Behold I am with you all days even to the end of the world.' For throughout the entire world, invisibly present to his disciples, he traveled on the sea of life, and in the many waters of the nations. This he accomplished by his invisible and hidden power."
Commentary on Isaiah- (from Bernard H. Cuneo, The Lord's Command to Baptize, An Historico-critical investigation with special reference to the works of Eusebius of Caesarea).

Isaiah 18:2 "This command seems to be given to the disciples of our Savior. Since they are messengers of good tidings, they are called messengers, and light ones, to distinguish them from the apostles of the Jews. Wherefore the prophet addresses these messengers of good tidings thus: You disciples of Christ, go as the Savior himself has commanded you; 'Go rather to the lost sheep of the house of Israel,' and 'Going make disciples of all the nations in My Name.'"

Isaiah 34:16 "For he who said to them, 'make disciples of all the nations in My Name,' also forbad them to establish churches in one and the same place."
