The Christian vision of love, so deeply personalistic and clearly emphasizing that the love of God and the love of neighbour cannot be opposed, has to take the social na-ture of man into account. If love is the centre of the Christian life and also points to the specificity of its vocation and mission, then it is impossible to imagine that this funda-mental life perspective does not find the right expression in relation to social life. This love should be expressed in a number of social attitudes, especially in those which are considered fundamental principles of social life. The ability to enact the principles of love is important in everyday social life. It involves multiple specific attitudes. This paper discusses – in the light of the encyclical Deus Caritas Est and Caritas in veritate by Pope Benedict XVI - the issue of love in three aspects: love in micro-relations, love and justice in macro-relations and love as a common good in macro-relations.
