No, not every Christian christens their child.
Here's a breakdown of why:
* Different denominations: The practice of christening (also known as infant baptism) is common in many Christian denominations, such as Catholicism, Eastern Orthodoxy, Anglicanism, and some branches of Protestantism (e.g., Lutheranism, Methodist). However, other denominations, such as Baptists, Pentecostals, and some non-denominational churches, practice believer's baptism, which is the baptism of individuals who are old enough to understand and profess their faith.
* Theological differences: The main reason for the difference in practice stems from differing theological views on the meaning and significance of baptism. Those who practice infant baptism often see it as a sign of God's grace and a way of bringing the child into the Christian community. Those who practice believer's baptism believe that baptism should only be administered to those who have made a conscious decision to follow Christ.
* Personal choice: Even within denominations that generally practice infant baptism, some individual families may choose to delay or forgo christening for personal reasons.
