As noted above, in Christianity, Universalism, Universal reconciliation, or universal salvation, is the doctrine that all will be saved. Among theologians the doctrine is often referred to using the Greek word apocatastasis. The doctrine addresses the problem of Hell and notions of God's mercy and justice. Universalists contend that a loving God would not submit anyone, regardless of his or her sins or beliefs, to everlasting torment. Some also argue that eternal condemnation in Hell, an infinite punishment, is not proportionately just with any number of essentially finite sins.
This idea is obviously not biblical and a good example of extracting some verses out of the Bible and ignoring the rest. It separates salvation from faith in Jesus and denies that any will perish.
And yet we know:
Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. This man came to Jesus by night and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him." Jesus answered him, "Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." John 3:1-3
"Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.” Matt 7:13-14
And if your eye causes you to sin, tear it out. It is better for you to enter the kingdom of God with one eye than with two eyes to be thrown into hell, 'where their worm does not die and the fire is not quenched.' Mark 9:47-48
This idea of universal salvation is not all that much different that the home-brew God I described in The Gospel According to Me. The idea has just been reinforced with some out of context bible quoting making it in my mind more grievous than the home-brew God.
