The act of partaking in communion, also known as the Lord’s Supper or Eucharist, generally presupposes prior baptism within many Christian denominations. Baptism serves as an initiatory rite, signifying entry into the Christian community and identification with the death and resurrection of Jesus Christ. Therefore, participating in communion often carries the implicit understanding of prior adherence to this foundational sacrament.
Historically and theologically, the practice of restricting communion to baptized believers stems from the understanding of communion as a symbol of unity within the body of Christ. Early church practices emphasized a shared faith and commitment, demonstrated through baptism, as prerequisites for participating in this sacred meal. This perspective reinforces the notion of a covenant community where members share in common beliefs and practices.
