As recorded by His one, holy, catholic and apostolic Church, present when these events occurred, in the eighth chapter of the Gospel of Mark Jesus relates seeing to comprehending.
In verses 17b-18, when His disciples did not understand a particular remark He made in regards to the difference between the ways of the religious and political rulers and His way, Jesus replied to His disciples, “Do you still not see or comprehend? Are your minds completely blinded? Have you eyes but no sight? Ears but no hearing?” Then first with His words (19-21), and then with His works (22-25), Jesus began to piece together the visual connection between faith and reason. His words and works always go together, because Jesus is God and there is no duplicity in God. In God there is total integrity.
Verses 22-25: “When they arrived at Bethsaida, some people brought Him a blind man and begged Him to touch him. Jesus took the blind man’s hand and led him outside the village. Putting spittle on his eyes He laid His hands on him and asked, ‘Can you see anything?’ The man opened his eyes and said, ‘I can see people but they look like walking trees!’ Then a second time Jesus laid hands on his eyes, and he saw perfectly; his sight was restored and he could see everything clearly.”
Among other things, these verses show us that there are two interrelated parts to seeing/comprehending. The first part is the ability to see at all; this sight marks the contrast between vision and total blindness. The second part of ‘seeing’ is the ability to correctly interpret, and thus comprehend, what we are seeing/perceiving with our senses.
In these verses people brought a blind man to Jesus. Jesus first healed the man’s total blindness and the man was able to see, but the man, though he could see, informed Jesus that he could not correctly interpret what he saw because his perception was askew. So Jesus then healed the man’s perception so the man could then correctly interpret the information his sense of vision gave him, which enabled the man to comprehend what he saw.
Likewise, one can look at Sacred Scripture and give to it some askew meanings, but without a humble and contrite relationship with God the Father, one will not be able to correctly perceive and interpret what one sees in the word of God. This is because without a soft heart towards our Lord God, Jesus Christ, which includes a humble thankfulness and praise for the Sacramental economy that He instituted through the primacy of Peter as is evidenced in the traditions of His one, holy, catholic and apostolic Church, there will remain, because of concupiscence, a disconnect between one’s faith and reason.
Right after His teachings about ‘seeing’ Jesus checked His disciples’ progress in comprehending His identity. He did this by asking His disciples to perceive the difference between “Who do people say that I am?” and “Who do you say I am?” Jesus’ lessons were effective: this time there was better understanding, in fact, Peter not only got it exactly right, but also correctly interpreted Old Testament prophesy in doing so- “You are the Messiah!”
Because of the highest quality of visual acuity in Peter’s answer, Jesus replied, “Blest are you, Son of Jonah! No mere man has revealed this to you, but my heavenly Father. I for my part declare to you [“you” here is singular in the Greek], you are ‘Rock,’ and on this rock I will build my church, and the jaws of death shall not prevail against it. I will entrust to you the keys of the kingdom of heaven. Whatever you declare bound on earth shall be bound in heaven; whatever you declare loosed on earth shall be loosed in heaven” (Matt. 16:13-19).
Seeing that His disciples were correctly discerning His identity, He began to teach them more about His purpose and plan, and the purpose and plan for His one, holy, catholic and apostolic Church to reveal His identity, loving forgiveness and unreasonable mercy to the world.
“‘Let us rejoice and be glad, and give Him glory! For this is the wedding day of the Lamb; His Bride has prepared Herself for the wedding. She has been given a dress to wear made of finest linen, brilliant white.’ (The linen dress is the virtuous deeds of God’s saints.) The angel then said to me: ‘Write this down: Happy are they who have been invited to the wedding feast of the Lamb.’ The angel continued, ‘These words are true: they come from God’” (Rev. 19:7-9).
From His resurrection to this day His Bride continues to teach His words with Her words and works, “Let me solemnly assure you, if you do not eat the flesh of the Son of Man and drink His blood, you have no life in you” (John 6:53).
My own faith walk alone proves that it is worth it to not suppress the truth about God. See with integrity and confirm the full deposit of faith that is given to you by Her in your baptisms, for the angel said, “‘Come, I will show you the woman who is the Bride of the Lamb.’ He carried me away in spirit to the top of a very high mountain and showed me the holy city Jerusalem coming down out of heaven from God. It gleamed with the splendor of God…I saw no temple in the city. The Lord, God the Almighty, is its temple –He and the Lamb. The city had no need of sun or moon, for the glory of God gave it light, and its lamp was the Lamb….but nothing profane shall enter it, nor anyone who is a liar of has done a detestable act. Only those shall enter whose names are inscribed in the book of the living kept by the Lamb’” (Rev. 21:9b-11a, 22-23, 27).
