The study tries to analyze main features of the Muslim immigration to Europe, which has as yet reached its highest point in 2015. The multiple problems it represents are examined with reference to the on-going history of changing patterns and motives of the migration, as well as of the accompanying ideological formulas coined nowadays by speakers of the migrants'second or third generation.
Some interesting items are mentioned in a brief survey. An attention is paid to attempts to arrange Muslims' attitudes towards their new European social environment into typological schemes, such as proposed by well-known researchers (Felice Dassetto, Mathias Rohe) and, on the basis of the specific Czech experience, by ourselves.
The rising Muslim presence had been carefully viewed and considered by Christian Churches and thinkers fairly earlier than it started to be a problem of wider concern. Christian opinions, however divided, do never decline to a level of an absolute refusal of help.
A constructive attitude, including a differentiation among migrants according to their compliance with European democratic standards, is an inseparable part of the Christian approach. In this respect, the study criticizes widespread negativism of the Czech politicians and large sectors of the public opinion towards needy refugees deserving merciful assistance.
