Regarding Islam’s denial of the crucifixion of life and the non-focus of the interior, again, we must discern…Here is a piece from the dogmatic constitution on Divine Revelation from Vatican II council.
This section is on ‘How God’s revelation is handed on’.
'Christ the Lord, in whom the whole revelation of the most high God is brought to completion, commanded the apostles to preach the Gospel to all mankind. The Gospel, promised through the prophets, was fulfilled in his own person and promulgated by his own lips. The apostles were to proclaim it as the source of all saving truth and all moral discipline, and in so doing to communicate the gifts of God to men.
This command was faithfully carried out. First, by the apostles, who in their preaching by word of mouth, their example and their instructions handed on what they had received from Christ’s lips, from his life among them and from his actions, or had learnt from the prompting of the Holy Spirit; then, by those apostles and apostolic men who committed the message of salvation to writing, under the inspiration of the Holy Spirit.
To ensure that the Gospel might remain always alive and whole within the Church, the apostles left bishops as their successors, and made over to them their own position of responsibility as teachers. What was handed on by the apostles comprises all that makes for holy living among God’s people and the increase of their faith. So, in its teaching, life and worship the Church perpetuates and transmits to every generation all that it is, and all that it believes.
This tradition received from the apostles develops within the Church under the guiding presence of the Holy Spirit. Understanding the realities and the words handed down grows through contemplation and study by the faithful as they ponder them in their hearts, through deep insight into spiritual thinsg that they come to experience, and through the preaching of those who, with the succession in the episcopate, have received the sure charism of truth. Thus the Church throughout the ages is always advancing towards the fullness of divine truth, until the words of God are brought to completion within it.
The writings of the holy Fathers of the Church testify to the life-giving presence of this tradition as its richse flow into the life and practice of the Church, in its belief and in its prayer.
Through the same tradition the complete canon of the sacred books is made known, and Holy Scripture itself is understood in greater depth and becomes continuously alive and active. In this way God, who spoke in times past, continues to converse for ever with the bride of his beloved Son; and the Holy Spirit, through hom the living voice of the Gospel reechoes in the Church, and through the Church into the world also, guides the faithful into all the truth, and causes the word of Christ to dwell among them in all its abundance.’
Here is a letter of the Apostle Barnabas who replaced Judas Iscariot the traitor…
The New Creation…this letter was written in just so many years after Christ’s death and resurrection…Note the tone…it is the same as Vatican II’s, written almost 2,000 years later…
'The Lord was willing to hand over his body for destruction so that by the shedding of his blood we might be made holy through the remission of our sins. Acccording to Scripture, this refers both to Israel and us. [He was wounded for our transgressions and bruised by our iniquities; by his wounds we are healed. He was led like a sheep to the slaughter, like a lamb that is dumb before its shearer.] What a debt of gratitude, then, do we owe to the Lord for letting us see the meaning of the past, for instructing us about the present and not leaving us in ignorance about the future. In the words of Scripture: ‘Not unjustly are nets spread for the birds’. The means that a man is justly condemned, if knowing the right way, he heads into the way of darkness.
The Lord was ready to undergo suffering for our souls’ sake, even though he is the Lord of the whole earth, the one to whom God said at the foundation of the world: “Let us make man in our own image and likeness”. But, in that case, my brothers, how culd he allow himself to suffer at the hands of men? This is the explanation. The prophets inspired by his grace foretold what he would do; he allowed himself to suffer because he had to be seen in the flesh, in order that he might destroy the power of death and manifest the resurrection from the dead. In this way he would carry out the promises that had been made to our forefathers, and while still on earth prepare for himself a new people; he would also show that, after the resurrection, he was to be our judge. Furthermore, by teaching Israel and working such great signs and wonders, he proclaimed the good news and showed the depths of his love for that people.
Having thus renewed us by forgiving our sins, he refashioned us; he gave us souls of children, as though we had been born anew. For it is to us that the Scripture refers when the Father says to the Son: ‘Let us make man according to our own image and likeness; and let him rule over the beasts on the earth and the birds in the air and the fish in the sea’. The Lord saw the beauty of our fashioning and added: ‘Increase and multiply and fill the earth’.
All this God has said to his Son. But let me now point out to you how he also speaks to us. It is indeed a second act of creation that the Lord has performed in these last days; that is why he says, ‘Behold, I am making the last things like the first’. It was this that the prophet had in mind when he said: ‘Enter into a land flowing with milk and honey, and rule over it’. It is true, you see, that we have been completely remade. This is what God means by the words of another prophet: ‘Behold, says the Lord, I will take stony hearts out of this people’, that is, the people whom the Spirit of the Lord foreknew, ‘and put hearts of flesh into them’. For he willed to appear in the flesh and live among us.
And so, my brothers, the dwelling place of our hearts is a temple sacred to the Lord. Again, the Lord says: ‘Let me give thanks to you in the assembly of the people’. So it is we, whom he has led into the fertile land’.
The prophets referenced here share a very different perspective than Mohammed.
