Quote examples
Pierre Teilhard de Chardin
French Philosopher
When all is said and done, what constitutes the impregnable superiority of Christianity over all other types of Faith is that it is ever more consciously identified with a Christogenesis: in other words, with an awareness of the rise of a certain universal Presence which is at once immortalizing and unifying.
Quote examples
Maria Montessori
Italian Educator
