+xI think I believe in it. Does anyone know anything about it?
You might be interested in the rationale of the Protestant gospel (non-Catholic) that explains why reincarnation is considered a false concept held by other religions. It's not just saying other religions are wrong, but rather, the rationale for that assertion.
To begin with, the New Testament states:
"... it is appointed for man to die once, and after that comes judgment" (Hebrews 9:27, New Testament Bible)
i.e. there is no repeats and no cycles, in contrast to other religions and Catholicism which has a tradition of a further cycle known as purgatory.
It has to do with the legal argument: that no amount of good works can save you.
The legal premise is: after a person has committed the greatest crime/sin, no amount of do-gooding can outweigh the fact that justice must be brought to bear on that crime/sin.
For example, it's a legal principle that, for example, if a person kills someone, then you cannot cite a long list of good deeds to let you off the hook.
Sure. in a distorted legal system, criminals
are often let off the hook, e.g. when you read news stories of the most heinous crimes, and the weak-court gives them a slap on the wrist. But the general public's sense of justice criticises the weak-courts when justice has not been done. (In contrast, when the God of the Bible judges, there will never be an opportunity for anyone to accuse God of being un-just). Hence, God brings justice to every sin ever committed.
Hence, the God of the Bible offers Salvation, by sending his Son Jesus Christ who died in our place - and offers us a free gift, like a pardon. But a pardon given doesn't take effect unless the guilty-person accepts the pardon. i.e. Jesus has died and risen for you - and the offer of Salvation is made to you - but until you accept the pardon, it cannot take effect for you. God respects your free will.
Taking this notion - that "a major crime, cannot be outweighed by lots of do-gooding" - we see that 100% of all other spiritualities and philosophies are based on that opposite notion, that lots of do-gooding can let you off the hook. The basis of reincarnation is that, somewhere in one of the numerous future cycles, you live a good life, and then that makes you go upwards in terms of merit. At its root, reincarnation is saying: in one of those future cycles, your many good deeds will outweigh your bad deeds sufficient to let you go to a higher cycle.
But the gospel opposes reincarnation by its basis of law and justice: that a crime, once committed, cannot be outweighed by lots of do-gooding.
Even the Catholic tradition of purgatory - which the Protestant gospel opposes - is based on this flawed premise that, if you didn't make it within this lifetime, then in the "round two", if you are do good enough there, then you rise up to the next level. But the legal premise - that no amount of do-gooding can outweigh a major crime - that legal premise applies to this lifetime, and it would apply to purgatory as well. That is why the basic Protestant gospel opposes Catholic traditions.
That's a simplified summary of why the basic Christian (non-Catholic) gospel opposes the concept of reincarnation, which is regarded as a false-teaching. And Catholic purgatory is in essence another form of reincarnation for one more cycle.
Both purgatory and reincarnation are refuted by the Christian gospel which is based on basic legal principles, that once a major crime has been committed, justice is applied - and no amount of do-gooding outweighs it. Otherwise there will always be some who accuses the Judge of being weak and un-just. And God will never do anything that is not 100% just.
Hence, for God to combine being 100% just, and being 100% merciful, the only way for Salvation is summed in probably the most famous Bible verse:
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed. But whoever does what is true comes to the light, so that it may be clearly seen that his works have been carried out in God.” (John 3:16-21)
