Christ only taught "Elect", and that is His gold, so named due to His Salvific work. He makes no distinction, nor is there need of 'true' Elect, as the Elect are the same as "the few are chosen" - before Christ died for us, we were (and forever shall be) "the many called", as is the case for the everlasting Elect.
Figure that Christ had a small window of time to show the everlasting depth of His reign - He did not treat with disdain the fruit of His labor.
To speak of 'true' Elect is like trying to show that the Holy Spirit proceeds from the Son, when Christ only taught that He proceeds from the Father.
Though there have been universalists in devotion, I don't arrive at my conclusions specifically as a student of such councils. On the day He was crucified He said, "Where I am going, you cannot come." And only He who has come down from heaven can go up to heaven. On His way back up He went to hell for three days, even a minimal three days - but that was His first stop, so we cannot go to hell - He forbids it, He even says "I have set up a boundary not to be passed." Then is it seen in fulfillment "He shall save His people from their sins.", for all men have sinned and fallen short of the glory of God.
