***Your sweeping generalization that anyone who calls on Christ is a Christian is simply absurd. ***
Jailer: What must I do to be saved?
Paul: Believe on the Lord Jesus Christ and you will be saved.
If you won’t believe the Bible, you will believe anything else.
I believe in the Jesus Christ as found in the Bible. I believe that Jesus Christ saved me without my effort. I believe that I did nothing to warrant, invoke, instigate this salvation. I believe that Jesus Christ saved me because his Father told him too. I believe that Jesus Christ is the only begotten Son of God the Father and that he died for my sins. I believe that all of my sins have been paid for by Jesus on the cross, and I cannot do anything to purchase any minute amount of that salvation. I believe that when I die, I will be in heaven with God the Father and his Son by his side, and I will worship them forever and ever.
Now, my challenge: Which of these, if any, are heresy?
More fleeting generalizations. Let's see what the Bible says one must do to be saved (by no means an exhaustive list):
etc, etc. etc.
There are actually many, many more "prescriptions" given in the Bible that tells us what it takes to be saved...take your pick.

This is a Trinitarian heresy, dear friend. Christian understanding is that God the Father does not order the Word and the Spirit like some lesser "gods." God does not order Himself. God does not kill Himself to satisfy His own wounded "pride," nor does God use Himself as ransom to Himself to propitiate divine justice.

His sacrifice bought you a ticket to paradise. Whether you get there or not is up to you. You will have to work out your own salvation (Phil 2:12) through Christ.
