Protestant denominations have a core of common belief every bit as much as the different orders of Catholocism, so my depiction stands.

Protestant denominations do not have a core of common belief.

Do you believe the same as the Oneness pentecostals for example?

Since you don't know what religious orders mean in the Catholic (Or Orthodox) sense -- Ditto. I'm pretty sure it's just one of their numerous religious "orders" (denominations.) - let me explain:

Close to me, I have my parish that is run by Diocesan priests, while about 5 minutes walk away is a Franciscan monastery and a drive away is a Jesuit and a Premonstratian. The mass is exactly the same:

1. Entry prayers,
2. Readings from scripture (Old Testament, New Testament, Gospel) -- the same scripture readings everywhere
3. A sermon (this differs)
4. The central part of the mass - the partaken in the ONE sacrifice that Jesus gave of Himself in 33 AD on the cross
5. The communion
6. the blessings

To either the celebrant (i.e. the ministeral priest) or the laity the mass is exactly the same in all 4 of these churches despite the different orders - These can and should be considered like different regiments in the same army of Christ

The difference is the day to day lives of the clergy(whether priests or nuns or lay-brothers): Premonstratians and Benedictines are more contemplative, so a lot more time to community prayer and a rigorous schedule of prayer. For instance their day may look like:

5 am rise
5:30 - Morning payer
6:00 Holy Mass
7:45 breakfast
8:30 Morning chores, work
12:00 Mid day prayer
12:30 Spiritual readings
13:30 lunch
13:30 lunch14:00 Siesta
16:00 meditation/prayer
18:00 Private study of the scriptures
19:30 Supper
20:00 Night prayer (compline)
22:00 lights out

In contrast the Jesuits were originally formed as more active - and the Franciscans to be wandering preachers

So, the differences are more in the type of person who joins these orders

For a lay person, there is no doctrinal, dogmatic or even ritual difference between any of these orders

Now if you get to the Catholic "rites" - there are slight differences in the rituals: there are 23 rites - the largest and the one you probably only think of as "Catholic" is the Latin one, with reporting up through the Patriarch of the West (the Pope) to God. Others are the Byzantine rite, the Syro-Malabar, Syro-Malankara, the Maronite etc. rites each of which have their own Patriarch (and the Pope is technically only the first among equals there) and they have different ritual languages, some more elaborate rites etc., but the dogmas, doctrines are the same

ONE big surface difference is that the Latin rite is the only one with the DISCIPLINE i.e. non-dogmatic, non-doctrinal rule that the priests are to be celibate. Syro-Malabar Catholic priests can be married men who join the priesthood (as do the other non-Latin rite).

Now if you go to a Syro-Malabar mass and a Latin rite you will see the difference: even if both are in English. However the basic structure is the same: Prayers, readings, sermons, Eucharist/sacrifice.

Now in contrast, if you attend a Oneness Pentecostal service v/s a Southern Baptist vs a Orthodox Presbyterian Church service, the differences in dogma and doctrine are plausible and visible beyond the obvious ritual differences: these three have differences in fundamental beliefs.
