Hi @jongolson, thanks for the sincere question and for reading my reflection.

You’re right — Jesus never explicitly said, “You must worship on Sunday.”

However, Scripture shows that Jesus rose on the first day of the week (Matt. 28:1; John 20:1), appeared to His disciples that day (John 20:19), and the early Christians gathered on the first day to break bread (Acts 20:7). Paul also mentions the first day in 1 Corinthians 16:2, and John refers to “the Lord’s Day” (Rev. 1:10).

So for us Catholics, Sunday is about celebrating Christ’s Resurrection and victory over death. Jesus is also Lord of the Sabbath (Mark 2:27–28).

lol let's not make this a Sabbath and Sunday debate.

   Blessings!
