Catholic position about non-truthfully conversion to islam Two people, call them Jones (Catholic) and Fatima (Muslim), want to marry: first civilly and if the bishop gives a dispensation, religiously. 

Fatima is from a Muslim country that prohibits Muslim women marrying non-Muslim men, threatening that "crime" with severe punishment. In order for the civil marriage to be approved in Fatima's country, Jones (from a western country) decides to convert to Islam formally, as it is the only way he and his wife can stay in contact with Fatima's (non-devotional) Muslim family in the theocratic country.

What is the Catholic position about the acceptability of Jones' mimicked conversion to Islam while he still considers himself to be Catholic?
According to canon law on mixed marriages (i.e., marriages between a Catholic and non-Catholic),


  1917 Can. 1060 … if there is a danger of perversion to the Catholic spouse and children, that marriage is forbidden even by divine law.


Also—regarding the children, the procreation and education of whom is the primary purpose of marriage—it is required that


  1983 Can.  868 §1. … 2/ there must be a founded hope that the infant will be brought up in the Catholic religion…


Can that be said for a crypto-Catholic, pseudo-Muslim father living in an Islamic theocratic country? Wouldn't this be to tempt God?

The Church's laws on mixed marriages must be respected before attempting a clandestine marriage or a marriage under false pretenses.
