All the following Christian fathers contributed to the development of the Universal Community except …..St. GregotryPope John PaulSt PaulSt. Ambros

To determine which of the listed individuals did not contribute to the development of the Universal Community, we should evaluate their roles and contributions within Christianity.

1. St. Gregory: Often refers to figures like St. Gregory the Great. He significantly influenced the liturgical and pastoral aspects of the Church, contributing to the development of the Universal Church.

2. Pope John Paul II: He played a pivotal role in promoting ecumenism and was influential in advocating for the universal community, both within and outside the Catholic Church.

3. St. Paul: As one of the Apostles, St. Paul's letters and missionary work were instrumental in spreading Christianity beyond Jewish communities, thus shaping the universal nature of the Church.

4. St. Ambrose: He was a significant figure in the early Church and helped define the relationship between the Church and the state, also influencing the concept of the Universal Church.

Based on these contributions, all the individuals listed played a role in the development of the Universal Community, but it can be interpreted that St. Gregory might be contextually less recognized depending on how one views contributions differently compared to the others. However, if we interpret "Universal Community" strictly in historical terms, St. Gregory might be less emphasized.

Thus, the answer could be:

Final Answer: St. Gregory.
