How long are their services?
Could be an hour, 2 hours, or basically all Sunday with a break for dinner. Depends on the particular church and the particular “tradition” they are coming from.
My Sunday service lasts from 10:30 to 12:30 or 1:00. We’re not really sure when it will end because each service is different.
A typical service layout would be this:
Pre-service (many church’s will have a Sunday school)
Opening prayer
About 30 minutes for singing (traditional churches will play hymns and/or gospel songs, contemporary churches will play modern worship music, think Hillsong, with a praise team and band). You would see people raising their hands, singing or just standing quietly. During this time, depending on how “free” the church is, there may be people praying at the front of the church (the “altar”), there may be people crying or “shouting” (screaming and dancing in the aisles). There also may be praying in tongues or singing in tongues sprinkled throughout the service. However, keep in mind that in many Pentecostal churches you will see none of this highly emotional behavior.
Tithes and offering will be collected, a minister will probably offer some words at this point and prayer and then there will be singing while the collection occurs
There is often a point during the singing when congregants will be told to greet people. In some churches, you’re encouraged to walk around the church and hug people.
As a transition from the singing to the preaching, there may be special singing from talented church members.
The pastor or guest minister preaches the sermon on a particular Bible text or series of texts (it may be part of a sermon series or just topical or he might have felt an impression to preach on a particular topic). At the end, there will usually be some sort of offer to respond. If its an evangelistic sermon, people will be invited to come forward to pray for salvation and conversion. If its a sermon on healing, people may be invited to come forward for healing prayer and anointing with oil. If its a sermon on the Holy Spirit, people may be invited to pray for the baptism in the Holy Spirit.
There will be a closing prayer and a dismissal.
Some churches have a “children’s church” ministry that operates during the sermon. It’s supposed to provide age appropriate religious instruction, thought I’m sure if done poorly it just devolves into play time.
Pentecostal churches do not have Holy Communion every Sunday. Some do it monthly, quarterly or yearly. Baptism times vary but all Pentecostals believe in Believer’s baptism by immersion. Infants will be dedicated to God either during the main service or in a special service after the main service ends.
