A country of twenty million Latin-language speaking inhabitants, Romania is situated on the crossroad of different politic, religious and cultural influences. In the Moldavian and the Walachia principalities, the role of the Byzantine, the Ottoman, and the Russian Empires was essential. As for Transylvania, it was influenced by Vienna, Budapest and Rome. Unavoidably, this historic heritage is closely related to the Romanian religious situation.

In Poland, religious freedom is guaranteed by the 1997 Constitution and by international instruments incorporated into Polish law. The country is also party to most European and universal human rights documents. In 2003, the number of Catholics was estimated at 34,443,998 (90.1 % of the entire population), the number of Orthodox Christians at 510,712 (1.34 %) and the number of Protestants at 162,102 (0.42 %). Surveys of the Centre of Public Opinion Research (CBOS) and the Catholic Church Institute of Statistics have shown that 90 % of the Polish population consider themselves a religious person, whereas the latest CBOS survey (2015) reveals that 50 % of the population participates in mass at least once a week (58 % in 2005). The same survey indicates that the proportion of people who do not attend Church services has increased from 9 % in 2005 to 13 % in 2015. Daily prayer is also in steep decline: from 66 % in 2005 to 43 % in 2015.

Though the quantity of studies on religious/non-religious tendencies in today's Portugal is not overly abundant outside the Catholic remit, available are official and other reliable statistical data, and a number of well-structured analyses thereof, providing insights into the religious phenomenon in this country. Notwithstanding, the main issue is whether the more recent, few-decades-spanning information is by itself sufficient for supporting medium to long-term tendencies anticipation in this domain. This text takes the view that the Portuguese national historical context may to a good extent explain the degree of observed trend stability as regards religions-secularism in the country. The Portuguese law of religious freedom dates just from 2001. Signs are that only now an effective multiplication of creeds is underway, whose future impact cannot yet be soundly discerned.
