A fews questions to Jews who are no secular?

Just because Orthodox don't agree that someone is Jewish doesn't mean that they really aren't. You can be born Jewish and be Jewish, it depends on the lifestyle you live (culturally Jewish or not) and you can convert into any branch of JUDAISM and still be Jewish, because it is a branch of the same religion. Messianic Jews are a bit different. They may be considered Jewish because they were born Jewish, but the reason many Jewish sects reject them is because they reject the Jewish beliefs in One God. They reject the religious basis around Judaism and accept the cultural Jewish things. They SHOULD be called, Culturally Jewish Christians. Anyone who believes in Christ, is a Christian, it doesn't matter how they worship Christ, if they worship Him, that's what they are. Many Messianic Jewish rabbis study at Christian seminaries, this is why.
