One’s essential Jewishness is retained forever.
A Jew who ‘converts’ to Christianity may forfeit some treatment as a Jew (such as being buried in a Jewish cemetery), but need not convert to Judaism should he return to Torah observance. If female, her children will be Jewish.
There’s a lot of confusion because Israel is a secular state but finds it politically advantageous to pay a certain amount of respect to traditional Jewish law. That does not mean the government of Israel obeys Jewish law. Quite the contrary.
