This year, we commemorate the 450th anniversary of that pivotal decision to which the Carmelites were inspired by St Teresa of Jesus. In the current issue of our annual, this accounts for the publication of the text by Fr Ciro Garcia Fernandez. The author, a longstanding expert on the Reformed Carmel, sets out to present the charismatic journey of the Theresian Carmel using the life-stories and works of the key saints and blesseds of the Order. This approach of introducing the Theresian Carmelite charism on the basis of spiritual paths, itinera spiritualia, is wonderfully in sync with the line of our periodical which, as its title suggests, aims at presenting spiritual theology by looking at its expression in the lives of individual people. A similar idea lies at the root of the two articles about the spiritual life of St Raphael Kalinowski by Fr Jerzy W. Gogola and Eugeniusz Wilkowski. Fr Krzysztof Pawłowski discusses various explanations of the mysterious disease which afflicted St Therese of Lisieux at the age of ten. This issue of Itinera Spiritualia introduces also the third and last part of the interdisciplinary comparative study, spanning philosophy and theology, by Fr Albert S. Wach. Fr Rafał A. Wilkowski using the theological and the legal dogmatic method shows the proper understanding of autonomy and communion in the case of cloistered Carmel nuns. This issue closes with a biblical text by Fr Krzysztof Bieliński, C.Ss.R.
