I believe the original OP was supposed to be "
True Calvinism" & so I would prefer to discuss what a TRUE CALVINIST (and / or) a TRUE Believer in the Doctrines of Grace hold to.
Election....bottom line Ive been told that Election is not supported in scripture....I beg to differ.
Matthew 24:31 “And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.”
Ephesians 1:3-4 “Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love.”
Romans 8:33 “Who shall lay any thing to the charge of God’s elect? It is God that justifieth.”
Romans 9:11 “(For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth

”
Titus 1:1-2 “Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God’s elect, and the acknowledging of the truth which is after godliness; in hope of eternal life, which God, that cannot lie, promised before the world began.”
1Peter 1:2 “Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.”
OK, so it's taught in the Scriptures & the "True Calvinist" would attest to it.
