Will the YWAM shooter go to heaven?

I presume the knee-jerk response to this question is a loud "No!" But it's more complicated than that. He was raised in a Christian home, was home schooled, attended church most of his life, and attended a Christian college. What is not known at large at this time was whether he made a profession of faith or was baptized ( a form of public profession). Most Christian college applications require a testimony of one's coming to faith. The other extreme answer, "Yes!", comes from the subscribers of theology who believe "once saved, always saved." But this position is nuanced by those who find situations like this and, in order to save the theology, conclude any proclamations of faith were external and not internal, essentially, the hypocrisy eventually caught up to him. He was an actor, and not a true believer. Those of more ancient persuasions may consider him apostate.

Here is a useful history of apostasy from the Catholic encyclopedia.

Perfidiæ is the complete and voluntary abandonment of the Christian religion, whether the apostate embraces another religion such as Paganism, Judaism, Mohammedanism, etc., or merely makes profession of Naturalism, Rationalism, etc. The heretic differs from the apostate in that he only denies one or more of the doctrines of revealed religion, whereas the apostate denies the religion itself, a sin which has always been looked upon as one of the most grievous. The "Shepherd" of Hermas, a work written in Rome in the middle of the second century, states positively that there is no forgiveness for those who have wilfully denied the Lord. [Similit. ix. 26, 5; Funk, Opera Patrum apostolicorum (Tübingen, 1887), I, 547]. Apostasy belonged, therefore, to the class of sins for which the Church imposed perpetual penance and excommunication without hope of pardon, leaving the forgiveness of the sin to God alone. After the Decian persecution (249, 250), however, the great numbers of Lapsi and Libellatici, and the claims of the Martyres or Confessores, who assumed the right of remitting the sin of apostasy by giving the Lapsi a letter of communion, led to a relaxation of the rigour of ecclesiastical discipline.

This implies that salvation can be lost with the wild card exception that God can grant forgiveness. There are verses that apply to this situation specifically. 1 John 3

* 10. By this the children of God and the children of the devil are obvious : anyone who does not practice righteousness is not of God , nor the one who does not love his brother .
* 11. For this is the message which you have heard from the beginning , that we should love one another ;
* 12. not as Cain , who was of the evil one and slew his brother . And for what reason did he slay him? Because his deeds were evil , and his brother's were righteous .
* 13. Do not be surprised , brethren , if the world hates you.
* 14. We know that we have passed out of death into life , because we love the brethren . He who does not love abides in death .
* 15. Everyone who hates his brother is a murderer ; and you know that no murderer has eternal life abiding in him.
* 16 We know love by this , that He laid down His life for us; and we ought to lay down our lives for the brethren. (NASB)

Perhaps these verses settle the issue for those would condemn the killer to hell, regardless of his prior profession of faith. Roommate reports of his behavior, including hearing voices in his head, make one wonder about mental illness or spiritual oppression. Does brain chemistry gone haywire negate prior beliefs? We are not smart enough to discriminate between body, soul, mind and spirit. Hence my answer to the question is only God knows.
