I'm not seeing that in that passage. I see it as referring to little children as it states. I don't understand how you are seeing this passage as describing adults as "little children." I believe you are imparting your own theology into the text.
Sorry, I'm just going to have to agree to disagree.
I am far from the only person that sees "little children" in the context refers to disciples with child like faith, a spiritual child. That is a reason why I included two commentaries that say what I am saying. Infants and small children do not have the reasoning skills, comprehension skills required to have faith.
Matt 18:
--Jesus compares disciples "like children" v3
--receiving a disciple is like receiving Jesus v5 (see also Matt 10:40)
--warns about causing a disciple to sin , v6ff (infants, small child unable to sin)
--instructs about a disciple/brother that will not repent v15ff
--how to treat disciples that do repent v21ff
Clearly to me the context is not about infants/small children but disciples as spiritual child.
Mark 10:13-16 is Mark's account. After blessing the children the rich young ruler comes to Jesus but leaves in sorrow not willing to do what Christ told him to. Jesus then says "
How hardly shall they that have riches enter into the kingdom of God!" Mk 10:23. Then we are told verse 24 "
And the disciples were astonished at his words. But Jesus answereth again, and saith unto them, Children, how hard is it for them that trust in riches to enter into the kingdom of God!"

It could also be that Christ in Matt 18 context is talking about those who had just newly become Christians, Peter refers to them as "newborn babes" 1 Pet 2:2.
======
Matt 18:14 "
Even so it is not the will of your Father which is in heaven, that one of these little ones should perish." Infants/small children have no sin, they are innocent before God and if one dies as an infant he will not perish (
apollymi) but will be saved.
This means that "little children" here must refer to disciples that are capable of having faith but becoming lost as a sheep vs12-13. (A good knock against the forbidden forum topic.)

If Matt 18:3-6 is taken literally does that mean only "little children" (age wise) can enter the kingdom but not adults?
