So I've been thinking about this a lot lately...I discussed this with a friend a few months ago. We were talking about how many Christian groups (as you well know) have condemned HP as anti-Christian. In fact, I believe that the Harry Potter story is actually a symbolization of the Christian religion.
Note: This is entirely my opinion and is not meant as "Christian propaganda" or to offend anyone in the slightest. It is merely my opinion! :)

Harry Potter is Jesus. Whaaaaat?!
1) Both HP and Hesus were born into humble beginnings.
Hesus was born in Bethlehem, a tiny town literally in the middle of nowhere. There were no rooms for Mary and Joseph in any of the inns so they had to stay overnight in a stable where Mary gave birth among the mga hayop to Hesus where he was placed in a manger. He grew up in a plain and simple environment, no one who noticed him would think that he would become the Savior of the world. Harry too, was born to an ordinary family. He was also raised outside of the wizarding world (by muggles!) and did not look like he would one araw be their savior.
2) Both had to sacrifice themselves for the greater good.
The entire purpose of Jesus' life was to provide the greatest sacrifice: his own life for everyone else's. When he sacrificed himself, he saved the rest of the world from sin and therefore, death. Harry too, had to face death and be killed sa pamamagitan ng Voldemort in order to save the lives of everyone else; once Harry discovered he was a horcrux, as long as he lived, Voldemort survived.

3) Both of them rose from the dead.
After Hesus died on the cross, he rose from the dead 3 days later. Harry too, after Voldemort killed him in the Deathly Hallows, came back to life.
4)Harry's scar/the mark of God
In the book of Revelation, it states that those who follow God will receive his protective mark that will keep them ligtas from God's judgments on unbelievers and the Anti-Christ. Harry's scar is also a protective mark on him, a symbol of his mother's pag-ibig which helps keep him ligtas from Voldemort and gives him the weapon of love.

Dumbledore is God. No, really. He is.
1)Both were in control all along.
God had a purpose for having his only son, Jesus, come to Earth. He knew how things needed to go and gave Hesus the power to perform miracles. Dumbledore, like God, knew what was going to have to happen. He gave Harry the power to fight Voldemort (memories in the Pensieve, the resurrection stone, etc) and taught Harry how to think in order to defeat Voldemort.

2) Dumbledore is the symbol of good.
God is the Father of all and the direct opposition to Satan, the symbol of evil. No matter what happens to Harry in the first 6 books, he always has Dumbledore to turn to for guidance and support because Dumbledore is promoting good over evil.
3) My God, my God why have you forsaken me?!
These words were spoken sa pamamagitan ng Hesus on the cross; as he was carrying the burden of the sins of everyone God turned away spiritually from Hesus (but NOT permanently). Harry too, felt abandoned sa pamamagitan ng Dumbledore in the 7th book because he felt that there were many things that Dumbledore did not tell him or prepare him for.

Voldemort is such a slithery serpent!
1) Both are very, very tempting.
Hesus led a perfect life, but not without temptation. The Devil tried to trick him, tempt him (i.e. offering him water if he bowed down to him in the desert after Hesus was fasting for 40 days and 40 nights). There were plenty of opportunities for Hesus to give up and turn to Satan. Harry, too, was tempted sa pamamagitan ng Voldemort on multiple occasions to give up and give into him, even sumali his side! But Harry didn't.

2) Both are symbols of evil.
This is relatively self explanatory; Satan represents the evil in the world as does Voldemort in HP world.
3)Both are "fallen angels."
Satan (Lucifer) used to be a angel; he was one of the most powerful in Heaven and God trusted him. But when Lucifer decided that he was better and attempted to have God usurped he was cast out of Heaven along with his demons to Hell. Voldemort, too, was a very special wizard that had special talents and Dumbledore looked on him as a promising student. But when Voldemort attempted to gain madami power than he should have, he nearly Nawawala his life trying to kill Harry and was thrown into oblivion for nearly 11 years.

Some madami parallels:
1)Disciples/Dumbledore's Army
Jesus' disciples were chosen to follow Hesus and help him spread the word of God. They were ibingiay the power to perform miracles and stood sa pamamagitan ng Hesus and Jesus' cause. The D.A., too, was created sa pamamagitan ng Harry to stand for Dumbledore and the cause of fighting Voldemort in the face of evil.
2) Peter Pettigrew: Judas Iscariot?
Judas, one of Jesus' disciples, was trusted to help Hesus but instead betrayed him and gave him away to the guards so that Hesus could be arrested and crucified. P.P. was also a trusted member of the Order of the Phoenix and betrayed the position of Harry when he was a baby resulting in James and Lily's death and Harry's almost death.

3)The lion and the serpent.
In the Bible, and in the Christian world, Hesus is often referred to as the "Lion of Judah." In the Chronicles of Narnia, Aslan is also a representation of Hesus and is a lion. In the Bible, the Devil is represented as a serpent; he takes that form when he tempts Eve in the garden. In HP, the House of Gryffindor is not only the House of both Harry and Dumbledore, but a symbol of good. Most of the "good guys" come out of Gryffindor. Slytherin, in contrast, is the House of Voldemort and the "bad guys" and serves as the evil to Gryffindor's good.
4)Sword of Gryffindor/the Cross
The tumawid of Hesus is the representation of kristyanismo and used sa pamamagitan ng many (nowadays) to spread the "truth" of God and let others know that they follow God. The Sword of Gryffindor is used as "the sword of truth" in effect. It is what comes to the aide of Harry in multiple instances to help him defeat the Horcruxes. Dumbledore leaves it to Harry and without it, he never would have defeated Voldemort.
5) Muggles/Jews
Throughout history, the Jews have been persecuted sa pamamagitan ng Christians for not being believers in Christ (even though they too are the children of God). Hitler persecuted the Jews in an effort to create a perfect race. In HP world, Muggles are persecuted as the Jews are. In Deathly Hallows especially, the Death Eaters treat the Muggles like criminals and imprison them in order to "purify" the human race (sound familiar? :/)
6) HP vs. Voldemort: One of them has to go!
The book of Revelation in the Bible tells us that Hesus will come again one day, and there will be one last battle between Hesus and Satan in which Satan will be defeated and Hesus take back control of the world: everything will be good again. Harry too, after coming back to life, has to defeat Voldemort in one last battle. When he wins, he regains control of the Wizarding community, and everything is at peace.

I know there are probably plenty madami examples that i just didn't think of or missed, but I hope you got my point! I also want to point out that there are many differences between HP and the Bible and none of the examples i listed are perfect, but i think that the similarities were worth noting. Feel free to add madami if you have any! ;)
