In Catholic Social Teaching, (hereafter CST) the term “solidarity” makes explicit what is implicit in the Gospel sayings about losing ourselves for the sake of others – and in this way finding our true selves. It is about what it means to be fully human: we cannot be our own true selves outside of right relationships with others and with our environment. But the Gospel saying is not just an anthropological statement; it is a moral requirement; it leads to having life, or losing it; and it is a requirement of Christian discipleship. (cf Luke 9:23,24)
