Ruminator's question https://christianity.stackexchange.com/q/108102/117426 prompted me to compile a list of [Biblical passages](https://christianity.stackexchange.com/a/108109/117426) that discuss mysteries, hidden knowledge, secrets of the Kingdom, and related themes, as well as God's willingness to invite seekers to search these things out. Ruminator also assembled an extensive collection of passages in his own [answer](https://christianity.stackexchange.com/a/108106/117426) on the theme of mystery in the Bible. Interestingly, some of the answers and comments in the linked question appear to advocate a kind of cessationist position, suggesting that everything has already been revealed in the Bible, and therefore no mysteries remain to be disclosed (or so they seem to argue). With this in mind, I am interested in an overview of doctrines from various denominations—including Catholicism, Eastern Orthodoxy, and Protestantism—regarding the possibility of God revealing mysteries to spiritual seekers today. It is evident from the Bible that God has certainly revealed mysteries to individuals in the past—for example, Paul's experience of the third heaven in 2 Corinthians 12:2-4, where he received revelations not recorded in Scripture. The question, however, is whether this possibility is still considered viable today, doctrinally speaking, and what conditions, if any, are believed to govern access to such mysteries. Would it be reasonable for a spiritual seeker to earnestly desire the revelation of mysteries today, according to different denominations?

According to Bible Trinitarians, let's assume that there is Samuel the prophet(before he died) and Samuel the spirit(after he died), so after the medium at Endor called his spirit from the dead, he was still Samuel the prophet technically because he still prophesied onto Saul that he would die the following day. Can this analogy be applied to demystify the divine nature of the Holy Spirit as being the Father? That is because I am So Few Against So Many in the flesh but also the same person in the spirit for even that medium must have acquired the name of Samuel from Saul, I am still the same person but with a different essence? So the Spirit is still the Father but in a different essence? Does this explain why the Father is not mentioned in the sermon about the unforgivable sin? Because he is literally the Holy Spirit? There is Jesus who was dead on the cross and Jesus who descended into the heart of the earth in spirit form, both were still Jesus.

Some random quotes from online Trinitarian sources. >The mystery of the Most Holy Trinity is the central mystery of the Christian faith and life. >The most profound and mysterious doctrines of the Christian faith: the Trinity. >The mystery of the Trinity doctrine is the manifestation of three distinct persons in one God. Given the very specific statements of Jesus who declared the Father was the only true God, with no mention of a spirit 'person', and literally *excluding* himself from being God, this biblical evidence from the 'only Savior and Lord' would seem a sufficient explanation. The Biblical evidence describing the one God, Yahweh, is not a mystery, Jesus is not a mystery especially as his God is the same as ours. The Apostles affirmed these simple truths, especially about the man Jesus, who again, is never described as God, so no mystery there either.
