Is it permissible to eat meat offered by a Christian family in a non-Islamic country, given the doubt about the method of its slaughter, and the inability to afford or access halal food?

Meats in European countries are permissible (halal) if the animals are slaughtered according to Islamic law (dhakāt shar‘īyah) by the People of the Book. If there is doubt whether the meat was slaughtered lawfully or not, there is a difference of opinion: some scholars, such as Ibn Humayd and Al-Fawzan, view it as impermissible until it is clarified that it was slaughtered lawfully, reasoning that the default ruling for meats is impermissibility. Others, such as Ibn Baz and Ibn Uthaymeen, view it as permissible in cases of doubt, considering the default ruling for the slaughtered animals of the People of the Book to be permissibility, citing Allah's saying: "The food of those who were given the Scripture is lawful for you." The second opinion offers more ease for people. It is not appropriate to refer to Christianity as "al-Masihiyya" (Messianism).
