Calvinism is another great heresy polluting the Church to this very day.
It is very cranky, but if you ever hear of it, steer clear!!
It is full of false tenets, probably the worst of which is that some people are predestined to the eternal flames of Hell.
Generally speaking you are unlikely to find a proponent of this doctrine today, but it still percolates into some people's thinking.
God does not predestine people to God to hell . He has mercy and therefore grace on "as many" as the father gave him .
The key is how many? Which is not universal-ism.
Revelation 3:19 As many as I love, I rebuke and chasten: be zealous therefore, and repent.
Those who he does not love he does not rebuke.
alatians 3:27 For as many of you as have been baptized into Christ have put on Christ.
Not all that sprinkle water on ones skin, just the many .
Romans 8:14 For as many as are led by the Spirit of God, they are the sons of God.
Those not led by the Spirit are not sons of God.
Romans 2:12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
John 17:2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
Not one more.
John 8:30 As he spake these words, many believed on him.
Only the ones that did believe as Christ gives the faith to make it possible. .
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
The ones that received His it came form his authority .The many who did not believe did not recieve power.
Matthew 20:28 Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
His ransom was not for the others, just the many that did believe.
