Baptism is a sacred ritual that was established by Christ. It entails the use of natural water and invoking the Most Holy Trinity. It's worth noting that anyone, regardless of their faith or beliefs, can conduct a legitimate baptism. Infants are eligible for baptism, and it is recommended because it cleanses them of original sin and all other sins, bestows grace upon them, and incorporates them into the Church. Baptism is considered essential for salvation and establishes a lasting connection with the Church.
