Acts 3:1 has Peter and John going to the temple for prayer. From this I assume that they no longer participated in the animal sacrifices at the temple because of Jesus’ perfect sacrifice for us on Calvary’s cross. The disciples, however, must have participated in the animal sacrifices prior to the crucifixion. But did Jesus, as an observant Jew, also participate in the sacrifice? He did not need any forgiveness but did he do it in order to “fulfill all righteousness” as he said to John at his baptism?
The Bible speaks of Jesus participating in Passover on the year He was crucified, and being present at the Feast of Tabernacles (John 7), and Hanukkah (John 10:22-23) at least once each. There’s no record of His other activities as an observant Jew except for His attendance at weekly Sabbath services (Luke 4:16).
