Inquiry was made among spirits about the disciples, for the purpose of teaching those who were from the planet Jupiter why people of lower condition, such as fishermen, were chosen, but not any from among the intelligentsia. Having heard them give the reason, I am free to repeat it here. It was because at that time, many were brought up learning a lot of nonsense and foolish ideas, to the point where they were unable to grasp matters of belief the way the uneducated do, who understand, and can believe them better. Therefore, they were chosen in preference to more educated people.
 There were twelve for this reason, that each one might portray the same quality as a tribe of Israel. Thus Peter portrays belief based on understanding, James charity, and John the fruits of charity. So with the rest. Therefore, such men were chosen as would resemble those whom they portrayed.

Someone of the Catholic religion came to me today, as almost every day several do from various religions, who have recently died. This one speaking with me was a Roman Catholic, and the conversation was about those who had been sainted on earth. He was told that no one in all of heaven is holy, other than the Lord, and angels being called holy is due to the holiness of the Lord, who is Holiness Itself; hence they are also called the Holy Spirit. Those of them who are angels declare that in them, there is nothing holy whatsoever, but filth, and that holiness belongs to the Lord Alone. It is known that angels are not holy, from the psalms of David [reference not found, perhaps Job 15:15].
 Then several of those who had been sainted on earth said unanimously, albeit with a rather mixed, almost stormy sound, that their holiness belongs to the Lord Alone, and that they are filthy, and due no honor.
 It was asked how it is with Peter, to whom were given the keys of the kingdom of the heavens [Matt. 16:19]. It was answered, that by Peter is meant belief, and that the keys to the kingdom of the Lord are given to faith, because no one can be admitted into heaven except by means of faith in the Lord, and no one but the Lord gives belief. Therefore the Lord Alone has the keys of the heavens, and he gives heaven to whomsoever it pleases Him. Thus it is not in the hands of any man.
 Faith is meant by Peter, just as by the other apostles are meant religious qualities: as, for example, by James, charity, and by John, the fruits of charity, in which all the elements of Christian religion are embodied. For this reason, he was leaning on the Lord's bosom [John 13:23].
