“Come and show us your face, O Lord, who are seated upon the Cherubim, and we will be saved.”  Psalm 80:4

In the liturgical calendar, Advent lasts for four weeks. However, for Sister Marianna, this year it lasted only two weeks. On Saturday, December 11th Sister Marianna died peacefully at 7:12 AM. She had been hospitalized at St. John’s for over two weeks and returned to Loretto Home on Wednesday, December 8th under hospice care. Sister had asked to come home for her final days.

Sister Marianna, the former Gloria Kosior, was born in Whiting, IN, on August 4, 1922, the daughter of Albert and Anne Skrabala Kosior. She entered our Congregation on September 8, 1943, and professed her religious vows on June 13, 1946.

Sister Marianna received a Bachelor of Science Degree in Dietetics from Fontbonne College in 1949 followed by a Dietetic Internship at St. Mary’s Hospital, Rochester, MN. She earned a Master’s Degree in Administration from Notre Dame University in 1981.

Sister Marianna served as a Dietitian at HSHS hospitals in Illinois and Wisconsin early in her career. From1962-1968, she was the Administrator of St. Anthony’s Memorial Hospital, Effingham, IL. She served as Administrator of St. Mary’s Hospital, Decatur, IL from 1968-1969.  From 1969-1979, she served the Province as a Provincial Vicaress and Provincial Superior. She founded Hospital Sisters Health System in 1978 and served as Executive Vice President from 1979-1980, when she assumed the role of President until 1989. She was the Convent Librarian for many years and retired from active ministry in 2016.

Anyone who knew Sister Marianna knew that she was a very intelligent person with vision, determination and courage. She demonstrated that in founding HSHS as well as in her roles as Provincial Vicaress and Superior. She had broad interests and skills that included sewing, knitting, swimming and the study of language. She was a faithful adorer in the Adoration Chapel until her recent hospitalization. She prayerfully supported the health system and the congregation during her hours in the chapel.

She was preceded in death by her parents, a brother, James Kosior, two sisters: Loraine Duray and Rose Marie Koopman. She is survived by a brother, Albert Kosior, Crown Point, IN, a niece and a nephew.

Visitation will be held at St. Francis Convent from 4:00-7:00 PM with a Wake Service at 6:00 PM on Tuesday December 14th. The Eucharistic Celebration and Rite of Christian Burial will be celebrated by Father Dennis Koopman, OFM on Wednesday, December 15th at 9 AM in St. Clare of Assisi Adoration Chapel.

As we continue our Advent journey, may Sister Marianna enjoy her reward for her many years of faithful service to God and to our congregation.
