First To the Gentiles: John the Baptist?

In the Patreon Zoom Meeting on 11/30/2024 (see the primary post here) James Tabor pointed out that Matthew edited Luke to delete the references to John the Baptist potentially baptizing Roman soldiers; i.e. Gentiles.

Luke 3:12-14Matthew 3:7-10
7 John said to the crowds that came out to be baptized by him, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruits worthy of repentance. Do not begin to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham. 9 Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.”
10 And the crowds asked him, “What then should we do?” 11 In reply he said to them, “Whoever has two coats must share with anyone who has none; and whoever has food must do likewise.” 12 Even tax collectors came to be baptized, and they asked him, “Teacher, what should we do?” 13 He said to them, “Collect no more than the amount prescribed for you.” 14 Soldiers also asked him, “And we, what should we do?” He said to them, “Do not extort money from anyone by threats or false accusation, and be satisfied with your wages.”
7 But when he saw many Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruit worthy of repentance. 9 Do not presume to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham. 10 Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.

Was the Demonic Man the second Apostle to the Gentiles?

Mark 5:14-20

NRSV – 14 The swineherds ran off and told it in the city and in the country. Then people came to see what it was that had happened. 15 They came to Jesus and saw the demoniac sitting there, clothed and in his right mind, the very man who had had the legion; and they were afraid. 16 Those who had seen what had happened to the demoniac and to the swine reported it. 17 Then they began to beg Jesus to leave their neighborhood. 18 As he was getting into the boat, the man who had been possessed by demons begged him that he might be with him. 19 But Jesus refused, and said to him, “Go home to your friends, and tell them how much the Lord has done for you, and what mercy he has shown you.” 20 And he went away and began to proclaim in the Decapolis how much Jesus had done for him, and everyone was amazed.
