That's going too far, and really is what Lord Jesus meant when He said His Apostles hearts were hardened. He was referring to their having been given spiritual eyes to see, and ears to hear, but their heart was still trusting in men's traditions when they should have understood.
For example, with Jesus' miracle of the five loaves and two fishes, the punch line of His Message below is about the baskets that were left over...
Mark 8:14-21
14 Now the disciples had forgotten to take bread, neither had they in the ship with them more than one loaf.
15 And He charged them, saying, "Take heed, beware of the leaven of the Pharisees, and of the leaven of Herod."
16 And they reasoned among themselves, saying, It is because we have no bread.
The subject is Jesus using the idea of leaven in bread as a symbol for the false traditions of the Pharisees, and of king Herod's acts who married his own sister, which caused him to behead John the Baptist for, by which Herod's sister had recommended he do.
17 And when Jesus knew it, He saith unto them, "Why reason ye, because ye have no bread? perceive ye not yet, neither understand? have ye your heart yet hardened?
18 Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?
19 When I brake the five loaves among five thousand, how many baskets full of fragments took ye up?" They say unto Him, "Twelve."
20 "And when the seven among four thousand, how many baskets full of fragments took ye up?" And they said, "Seven."
21 And He said unto them, "How is it that ye do not understand?"
KJV
OK, so Jesus referred to the idea of leaven in bread, so that means consider how leaven in bread makes it artificially rise with many tiny air pockets in it to look like you're getting more bread, but in reality you are not.
Five whole loaves of bread went out to the multitude, but 12 baskets of fragments came back. In other words, there was much MORE BREAD that came back in the twelve baskets, but in fragments, i.e., in pieces.
Those baskets of fragments represent men's doctrines acting like 'leaven' added to the original five loaves of bread.
The Matthew 16 version of the above gives a bit more info showing Christ's Apostles after thinking about what He said, caught on to His Message of warning...
Matt 16:11-12
11 How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?
12 Then understood they how that He bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
KJV
Lord Jesus was simply using the analogy of leaven in bread to represent what the Pharisees and Sadducees were doing with their false doctrines and commandments of men.
