History of the  Office
             The focus on ecumenism in  the Archdiocese began in the aftermath of the Second Vatican Council.  It  was April 30, 1970, when Father Bernie Head (then on faculty at Marian College,  now University) went to Archbishop Biskup requesting the formation of an  Ecumenical Commission.  In his letter he made proposals for purpose,  membership, and effective diocesan-wide structure.
The focus on ecumenism in  the Archdiocese began in the aftermath of the Second Vatican Council.  It  was April 30, 1970, when Father Bernie Head (then on faculty at Marian College,  now University) went to Archbishop Biskup requesting the formation of an  Ecumenical Commission.  In his letter he made proposals for purpose,  membership, and effective diocesan-wide structure.
By 1972, the Commission was  meeting.  Initially, most members were clergy.  But rather quickly  local lay folks (e.g., Richmond, Terre Haute, New Albany) were added, as were  religious women, as had been suggested by Father Head.
Notable names soon emerged:  Fathers Richard Terrill (first chairperson), Mike Albright (second  chairperson), Tom Murphy (third chairperson), Msgr. Ray Bosler (expert at VCII  for Archbishop Schulte), Glenn Tebbe (director of the Indiana Catholic  Conference, retired 2021), and Sister Antoinette (secretary), among  others. 
The first years were spent  raising the consciousness of clergy, religious and laity to the “signs of the  times” in the ecumenical movement.  By January 1975, Ecumenical Guidelines  for the Archdiocese were promulgated.  Contemporaneously, a formal  Constitution and By-Laws of the Archdiocesan Commission were written and approved.
By 1976, an Ecumenical  Action Plan for parishes and institutions in the Archdiocese were in the  works.  Subsequent workshops were planned throughout the deaneries.   Resources for pastors and parishes were produced to help Catholics undertake and  understand the significant change in attitude toward ecumenical activities and  relationships, and to help the same understand what acceptable and unacceptable  ecumenical practices were.  Local dialogues were encouraged.   However, the winters of 1977 and 1978 were not kind to these efforts,  forestalling much of the hoped progress.
In the meantime, Father  Albright, Glenn Tebbe and Sister Antoinette began attending the National  Workshop on Christian Unity (NWCU) in 1974 in South Carolina. Each year the  Archdiocese was represented at this national meeting of Catholic, Episcopal,  Lutheran, Methodist and Presbyterian ecumenists.  In fact, the Action Plan  begun in 1976 was featured prominently at the 1977 (February) NWCU in  Pittsburgh, PA.
Further efforts for local  dialogue were set in motion.  A clergy retreat for Lutheran and Catholic  pastors was planned and executed by November 1976.  A comparable retreat  for Lutheran and Catholic Laity was to take place, but again the weather  conditions of two winters seem to have retarded these efforts.
By 1977, Fathers Terrill  and Albright had resigned for various reasons, and Father Murphy took up the  mantel of chairperson.  Msgr. Bosler remained active as well, being the  “face” in the “office of ecumenism”. 
1977 also saw the beginnings  of the formal Dialogue between Roman Catholics and Disciples of Christ in the  United States; the Disciples international headquarters were, and remain, here  in Indianapolis. 
It was in this same period  that a series of city-wide Prayer for Christian Unity prayer services  began.  Often co-sponsored by the Church Federation of Greater  Indianapolis and the Archdiocese, these prayer services continued for many  years each January, moving from church to church of various Christian  denominations.
As is wont to happen, the  passionate urgency which impelled the creation of the Commission, and its work,  began to wane.  By 1980, the Commission was moving to dormancy.  The  Office became the work more or less of Father Tom Murphy, assisted by Msgr.  Bosler.  Their efforts kept the Archdiocese involved in dialogue both  Ecumenical and Inter-religious.  The  first Catholic / Muslim gathering was through the efforts of Father  Murphy. 
The Archdiocese remained a  member of NADEO (National Association of Diocesan Ecumenical and  Inter-religious Officers – now CADEIO).  But the concerns of diocesan  life, the reduction in the number of priests and religious, and the struggle to  focus ecumenism and inter-religious efforts in the vast and varied reality of  the Archdiocese seem to have undermined the effectiveness of both Commission  and Office.
From the mid to late 1990’s  until 2012, most ecumenical and interreligious interactions were confined to            
            
              - local ecumenical and interfaith       prayer services, often at Thanksgiving, in parishes or deaneries.
- the annual Interfaith Thanksgiving       Prayer at SS. Peter and Paul Cathedral.
- ecumenical “moments” (e.g., the       installation or ordination of a new Episcopal Bishop or new Roman Catholic       Archbishop).
- the participation by Archbishop       Buechlein in the national dialogue between the Roman Catholic Church and       the Disciples of Christ.
In the  Fall of 2012, Auxiliary Bishop Christopher Coyne asked Fr. Rick Ginther to take  up the role of Director of Ecumenical and Interreligious Affairs.  
              From 2012  until the spring of 2016, the Office’s efforts grew slowly.  
              A revival  of the Week of Prayer for Christian Unity began in 2014 with the service at SS.  Peter and Paul Cathedral.  Each  successive January up to the present, the annual service is hosted by a  Christian denomination at one of their local churches in the greater  Indianapolis area.  Many leaders of  Christian denominations are leaders of some part of the service.  An organizational committee works each year  to plan the service based on the international service prepared by Faith and  Order (World Council of Churches) and the Pontifical Council on the Promotion  of Christian Unity (PCPCU).  To date,  host churches have been Roman Catholic, Disciples of Christ, Evangelical  Lutheran Church of America, American Baptist, Friends (Quaker), United Church  of Christ, Presbyterian (Covenant Network of Presbyterians), and Episcopal  Church.
              A weekly  column in the Criterion “Ut unum sint” began in September 2014.  Now in its ninth year, it continues to  explore various connections and concepts, both ecumenical and interreligious,  to share with the people of the Archdiocese. 
              In 2013,  the Office became a charter participant in the Festival of Faiths (Center for  Interfaith Cooperation).  This late  summer outdoor festival gathers people of many faiths together.  A common theme is established by the  organizers.  Participants from the  various religions in the Greater Indianapolis area witness to how they embody  the theme.  Through this effort, the  Archdiocese remains visibly connected to the many faiths nestled in the  Archdiocesan boundaries.
              Relationship  with the Center for Interfaith Cooperation was begun in 2011 by ICC (Indiana  Catholic Conference) through the presence of Glenn Tebbe (Director of ICC).  In 2018, having served his two 3-years terms,  Glenn stepped away from the CIC Board.  Father  Rick Ginther continued to be the CIC Board member officially representing the  Archdiocese.  This involvement, in many  ways, remains a shared outreach of the Office of Ecumenical and Interreligious  Affairs and the ICC.
              Through  involvement with CIC, the Archdiocese has cultivated young but deepening  relationships with the Muslim, Sikh, Jain, Hindu, Latter Day Saints, Pagan,  Buddhist, and Baha’i communities.
              A more  intentional connection with the Jewish community began in 2014 with  participation in the Jewish Film Festival.   Growing from that were encounters with the rabbis of the area, mutual  presence at interreligious prayer services praying for an end to religious  intolerance and terror, and invitations to attend major Jewish religious  festivals.  The Office began a  relationship with JCRC (Jewish Community Relations Council), which continues  yet today.  In 2019, the Office hosted a  luncheon for Archbishop Thompson and some of the Jewish Rabbis of the area,  with a promise of further such contacts.
              A special  relationship exists between Archbishop Thompson (and before him, Archbishops  Buechlein and Tobin) and many of the other Christian “judicatories” (leaders of  a denomination) who reside in Indianapolis.   They meet once a month on a weekday morning to share both common and  unique experiences.  Such gatherings are  essential building and sustaining such valued relationships.
              In 2016  the efforts of the office began to grow more substantially.  The director moved to Indianapolis (Our Lady  of Lourdes parish).  Spending most  Wednesdays in an office in the Catholic Center has enabled him to make more  significant contacts with a variety of others involved in ecumenical and  interreligious relations.
              In April  2017, an Advisory Board was formed for the Office.  Composed from the outset of clergy, religious  and lay men and women, the board serves the director in visioning how  ecumenical and interreligious relations can be encouraged and enhanced  throughout the Archdiocese.    The board  meets six times a year.  Recently the  board began to dedicate a part of each meeting to breakout groups, one  ecumenically focused, one interreligious focused.  This affords greater creativity and drive in  both areas.
              Relationships  with Butler University’s Center for Faith and Vocation, Marian University’s  Theology and Philosophy Department, and St. Meinrad School of Theology have  been nurtured since 2017.  Collaborations  have included exchange of speakers and promotion of events hosted on campuses.
              A new  endeavor (2022) of the Advisory Board is a closer relationship with all the  Catholic High Schools in the Archdiocese.   The office and board hope to be of assistance in raising awareness of  ecumenical and interreligious relationships that are possible among faculty and  students.  Opportunities for learning the  varied religious traditions of faculty and students at each campus is also a hoped-for  outcome.  A special encouragement for the  schools will be an annual ecumenical prayer service during the Week of Prayer  for Christian Unity (January 18 – 25).
            Additionally in 2022, the Advisory Board and the Director began creation  of parish contact persons (Parish Champions) throughout the Archdiocese.  These “champions” will be the first contact  for information sharing and event notifications with the Office.  It is hoped that they and their pastor / plc  will work together to build up local relationships with other Christian  churches, and where possible, local relationships with other faiths.
