They can edit their own versions to conform to their doctrines but what's stopping people to hand flyers or glue posters with the actual quotes in contradiction to their statements?

"31 And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven. 32 Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come."

"16 As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and alighting on him. 17 And a voice from heaven said, “This is my Son, whom I love; with him I am well pleased.”"

"Therefore, “soul” in the Biblical sense refers to the entire living being. If separated from the life force originally given by God, the soul dies.—Genesis 3:19; Ezekiel 18:20."
Plain lies.
"The doctrine of the immortality of the soul raised questions: Where do souls go after death? What happens to the souls of the wicked? When nominal Christians adopted the myth of the immortal soul, this led them to accept another myth—the teaching of hellfire.
FACT:At death a person ceases to exist"

"37 He answered, “The one who sowed the good seed is the Son of Man. 38 The field is the world, and the good seed stands for the people of the kingdom. The weeds are the people of the evil one, 39 and the enemy who sows them is the devil. The harvest is the end of the age, and the harvesters are angels.
40 “As the weeds are pulled up and burned in the fire, so it will be at the end of the age. 41 The Son of Man will send out his angels, and they will weed out of his kingdom everything that causes sin and all who do evil. 42 They will throw them into the blazing furnace, where there will be weeping and gnashing of teeth. 43 Then the righteous will shine like the sun in the kingdom of their Father. Whoever has ears, let them hear."https://www.biblegateway.com/passage/?search=Matthew+25&version=NIV
34 “Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35 For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36 I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’
37 “Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? 39 When did we see you sick or in prison and go to visit you?’
40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’
41 “Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42 For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43 I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’
44 “They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’
45 “He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’
46 “Then they will go away to eternal punishment, but the righteous to eternal life.”Many more examples and arguments against them can be found I'm sure.
