The following examples are based on "general" Protestant beliefs:

• The Lutheran Church believes in baptismal regeneration, the Baptist church does not.
• The Assembly of God denomination uses instrumental music during worship, the Church of Christ denomination believes instrumental music to be unbiblical.
• Presbyterians believe in unconditional atonement and irresistible grace, Methodists reject the two beliefs.
• The Lutheran church believes that worship should be liturgical, the Assembly of God church does not.
• The Church of Christ denomination believes that baptism should be administered by complete immersion only, Presbyterians believe pouring is acceptable.
• Methodists believe in the Trinity, Oneness Pentecostals do not.
• Lutherans affirms the fact that Mary remained a virgin throughout her life, Baptists reject this belief and say that Mary had other children.
• The Church of Christ denomination believes that baptism is necessary for salvation, the Baptist Church does not.
• The Methodist church accepts female ministers, the Baptist church reject female ministers as unbiblical.
• Episcopalians baptize infants, Pentecostals believe infant baptism to be invalid.
• The Baptist Church teaches that once a person is saved, he is always saved and can not fall from grace. The Church of Christ rejects this teaching as unscriptural.

With all these contradictors beliefs, there remains one common thing all these Protestants denominations believe. That is Sola Scriptura (the Bible and the Bible alone is the sole rule of faith). Although the above list is a "generalization" (for example not all Baptist are opposed to female ministers), it is accurate enough to demonstrate the result of sola scriptura. Is it not odd that all these Protestant Churches base their beliefs on the same Bible but yet their beliefs differ in so many ways? One final question, is this how God Fathers his family???
