But you cannot argue only on the basis of English meanings of words, when the Bible was written originally in Hebrew and koine Greek. It is necessary to consider how the word "true" is used in those languages, and whether it is in the exclusive sense implied by the English word. In such a case, a word's actual usage in the Bible has to carry more weight.
You cannot argue on the basis of the Bible's use of the word "true" that calling the LORD (Jehovah) "the only true God" makes Jesus a "false" God. It simply doesn't work that way. There are too many cases that prove otherwise, that "true" is not necessarily the opposite of "false." The context governs.
For example, when the writer of Hebrews (at 8:2, NASB) calls Jesus "a minister in the sanctuary and in the true tabernacle, which the Lord pitched, not man," he is contrasting this "true tabernacle" of Jesus with the tabernacle Moses pitched in the wilderness. But that tabernacle of Moses was also, according to the Bible, the Lord's true tabernacle, otherwise it would not have been used for worship. Was Moses' tabernacle therefore a "false" tabernacle? The Bible nowhere indicates this. Clearly, calling the symbolic tabernacle in which Jesus serves a "true" tabernacle does not mean that the tabernacle of Moses was a "false" one. There are many, many such examples of the actual use of the word "true" in the Scriptures.
I did not hear the program of which you speak. But if the objective was to somehow prove the Trinity from the Bible, it was doomed from the beginning. The LORD (Jehovah) is the only true God who must be worshiped. But Jesus is also a true god in that he is truly of divine nature and possesses the true attributes of divinity. It is not an instance of one postulate being "true" and the other being "false." Regardless of English usage, when dealing with the Bible, we have to look at instances of the Bible's usage.
