Can I be saved if I don't fully comprehend the Trinity?

I don't think so. There are two types of people in the world when it comes to how they understand the Trinity. The first type consists of non-Trinitarians who believe in the Trinity doctrine but have an incorrect view of it. The second type is the anti-Trinitarian group, which continues to oppose sound teaching about God despite its plain Scriptural interpretation. The second group is conceited and unyielding. Even if one has some inaccuracies in the Trinity, he has a better chance of redemption than those anti-Trinitarians who are arrogant enough to accept the truth. After all, we were saved simply by believing in the Jesus of the Bible. However, as our understanding of Christ deepens, He will undoubtedly reveal Himself to us in relation to the Father and the Holy Spirit. Even John's disciples are ignorant of the Holy Spirit, the third person of the Trinity. It is not that they oppose the Holy Spirit; rather, they are merely uninformed (see Acts 19:2).
