Are Mennonites catholic? (differences and similarities between Mennonites and Catholics)

As a theology scholar, I feel fulfilled when learning about different Christian doctrines. So, I decided to research different denominations, and last year, I took on the Mennonites. I wanted to learn all about them and how they differ from popular religions. Since there is little information about them, I decided to head to Amish County, Ohio, for a few weeks to interact with the Mennonites in person. So, last week, during our Q & A session on my online Interdenominational Forum, one member raised the topic of Mennonites. He said that Mennonites were Catholics, leading to a heated debate. Looking at the misinformation among the members, I decided to tackle this topic in-depth. Luckily, I was well versed with this group and easily answered any other questions asked. So are Mennonites catholic?

No, Mennonites are not Catholics. They are part of Anabaptists, which separated from Catholicism in the 16th Century.

Join me today as I inform you about the differences and Similarities between Catholics and Mennonites in this article. I will also talk about what Catholics think about Mennonites. Read on to find out more.

Their dresses are mostly homemade and have neutral colors. Whether in Church or not, these women have to cover their hair as a form of submission, especially in public spaces.


Catholics consider artificial contraceptives sinful; therefore, they are discouraged from using them. They are encouraged to practice natural ones, like using safe days. On the other hand, Mennonites are permitted to use artificial contraceptives.

Can Mennonites attend Catholic Church?

This depends on the person; it is their choice to do that, but there is no harm in attending a Catholic church as a Mennonite. In 2012, at the Bridgefolk conference, Mennonites and Catholics gathered at a chapel and held a double Super Service. The Catholic Priest and a Mennonite Pastor conducted the mass. It was like two services combined, and each side conducted their Service at their assigned time. The key difference lies in the theology of the Eucharist and Baptism. However, both churches worship God. Although you can choose which Church to attend, it is better to stick to one that nourishes your spirituality and avoids mixing.

Can a Catholic attend a Mennonite Sunday service?

As I said earlier, this decision is personal, but it is allowed since both churches share a common belief in Christ and the Holy Trinity. So you can choose to attend a Mennonite Sunday Service as a Catholic, but remember that there are some things you will not find in the Service. For instance, there will be no point where you will worship any saints in the Service. Also, attending their Service and participating in their holy communion will likely tamper with your belief. Unlike Catholics, Mennonites believe that the bread and wine symbolize Jesus Christ’s body and blood. Catholics believe that the wine and bread taken during communion literally represent the body of Christ and His blood. Therefore it is up to you to analyze what you believe in as a Catholic before attending the Mennonite Service.

What do Catholics think of Mennonites?

Catholics, led by the Pope, think that Mennonites are Christians like them, and God called both of them to be peacemakers among the believers. In 2012, Pope Benedict XVI said that he found it fit to start understanding their fellow Christians, Mennonites, and evaluate the causes of conflict between them so that they could solve it. According to the Pope, when both churches understand each other, they will be able to heal.

The reason for the conflict between the two churches is dated back to the 16th Century. Mennonites are part of the Anabaptists who were pulling out of the Catholic Church in the 16th Century because they were not in agreement about Baptizing infants. As they pulled out, the founders of Anabaptists were killed by European Catholic Governments, calling them heretics. Since then, Mennonites feel like the Catholic Church holds negative views about them.

In 2003, Catholics and Mennonites published a document about the peace they were working on. In 2012 the Pope said that both of them share a belief in Christ and there is no need for conflict. Since then, Catholics have thought highly of Mennonites.

Can you convert from being a Mennonite to a Catholic?

Yes, you can convert from being a Mennonite to being a Catholic. Even Pastors from Mennonite can convert to Catholicism. Harold Wenger, a man who used to be a Pastor at Mennonite, proves that it is possible to convert to Catholicism by narrating his drastic moves toward it. According to him, all the mix-up in leadership in Mennonite churches was so draining and complicated. He was at peace when he found a functional leadership structure in the Catholic Church. Also, he says that he converted to Catholicism to feed his Spiritual Hunger which was achieved through the Eucharist. Therefore, there is a chance for any Mennonite to become. Catholic.
