<snip>But it would be interesting to hear his response to these two questions:
1. Am I a Christian if I do not believe in the Trinity, as long as I believe everything the Bible has to say about the Father, the Son, and the Holy Ghost?
2. Am I a Christian if I believe that my faithfulness to Jesus Christ is the only true measure of my degree of faith in Jesus Christ, and that if I consistently fail to repent of my sins, my faith will get me no where?
I haven't read further than this yet, so I don't know if Ratiocinative has answered. However, here are MY answers, for what they are worth:
1. Hard to say. If you don't believe the Trinity, you do not believe "everything the bible has to say about the Father, the Son, and the Holy Ghost." Indeed, you are resisting the witness of scripture to the Son. For the bible does not affirm the physicality of the Father or the Holy Ghost. According to the bible, there is one and only one divine being, who is a
spirit and exists eternally as three distinct persons. One and only one of those persons has experienced physicality. To deny this is to separate yourself theologically from the community inaugurated by Jesus.
But are you in good standing with God? Well, that's another question. I'd say that it's not my place to judge. It is God's place. God will judge you based on the totality of your life lived. Christians and non-Christians (however those categories are understood) will all be judged on the same basis. God does not play favorites.
It's also possible, I think, for persons to be deceived in matters of spirituality and religion. It's also possible to in all good faith not be able to buy into "correct" theology. (I'm assuming for the moment that the Trinitarian doctrine is correct and considering a person who doesn't buy into it even after sympathetically trying to learn and understand it.) I'm not convinced that either of those types of people are automatically damned.
2. Your status as a Christian doesn't depend on your theology of salvation. It depends entirely on having saving faith in Jesus, i.e., faith that produces deeds worthy of repentance. There are plenty of Christians who unfortunately labor under the impression that they are not because they have a skewed theology that tells them that unless they are perfect, God cannot receive them. And vice versa. Some people call themselves Christians, but they don't have the right to because they live in a way completely contrary to the will of God and have no compunction about it whatsoever.
I fully agree with the theology implied by your statement, though. Faithfulness to Jesus is the only measure of one's faith. Your feelings can be deceptive. No burning in the bosom or ecstatic experience (speaking in tongues or whatever) can provide a foundation for one's confidence. Rather, you must be able to look at your life and see a track record of improvement, sensitivity to moral upbraiding, and a growing pattern of repentance and forgiveness.
