What is the relationship between 1 John 2:2 and Calvinism?

1 John 2:2 is often referenced in discussions about Calvinism because it speaks about Jesus being the atoning sacrifice for the sins of the whole world. This verse is sometimes used to support the Calvinist doctrine of limited atonement, which teaches that Jesus' sacrifice is only for the elect. However, others interpret this verse differently and do not see it as necessarily aligning with Calvinist beliefs.
