The author of the article points to the value of the monstrance founded at the beginnings of the Congregation of the Handmaids of the Sacred Heart, whose decorative details and ornaments have their source in the regulations of the Congregation. The monstrance has become a graphic medium of spirituality by presenting the veneration of the Sacred Heart of Jesus, the Evangelical roots of the Congregation and following the example of the saints set as role models by the founders of the Congregation, St. Józef Sebastian Pelczar and Bl. Klara Ludwika Szczęsna. Apart from the iconographic meaning and thanks to a detailed research, the author also presents the material used to make the monstrance and the workshop where it was made.
