I am looking for help obtaining proof for a series of claims that Catholics make about how the early church conducted their services.
Context: I am a catechumen of the Catholic Church and also a student at a very Protestant college in America. For a final paper, I wrote an essay on how Catholics and Magisterial Protestants mirror the early Church in how they conduct their services.
The Problem: I just discovered that my professor is a Zwinglian charismatic who believes that the Catholic Church corrupted the liturgy in the 2nd or 3rd century. This means (in the professor’s eyes) that any secondary source that tries to show how the early church is similar to Catholicism must be biased or wrong. As such, I have been told that if I do not provide more primary sources for the historical arguments I make, the paper will not get a good grade.
I need primary sources for the following claims:
- Liturgy in the early church did not develop spontaneously
- Liturgy in the early church was divided into the Liturgy of the Catechumens and the Liturgy of the Eucharist
- The Liturgy of the Catechumens had been drawn from synagogues.
- Christians initially worshipped in synagogues, and drew parts of the Christian services from there
- Liturgy of the Eucharist was generally uniform in how it was conducted
- Liturgy of the Eucharist followed the pattern of the last supper
- Liturgy of the Eucharist typically came after the Liturgy of the Catechumens
- An altar and vessels were used in the Liturgy of the Eucharist
- The agape love-feast was generally uniform in how it was conducted
- The agape love-feast died out because of abuse
- There were set aside times for prophesying and speaking in tongues
- Times for prophesying and speaking in tongues died out because of abuse
I would appreciate any help in recovering evidence for this. I only have a few days to fix the paper.
