Why did early Christians in Acts still go to the Jewish temple every day?

There were not Christians/crestianus; they were mostly Jews (some Gentiles, but mostly Jews) who just as Yeshua (Jesus) did continued to go to Temple and attend synagogue every Shabbat to hear Torah, Acts 15:20-21.

The early believers considered Jesus to be the Jewish Messiah, and the most natural thing in the world was to continue to worship in the Temple. The problem with all the answers above is the assumption that Jesus fulfilled the sacrifices. But there are major problems with this view. The Law and halakhah laid down strict rules for the temple sacrifices, and the death of Jesus violates just about every one of them.

1. Jesus wasn't killed in the temple;
2. Jesus was killed by the Romans and not a priest;
3. Jesus was not physically unblemished, but seriously physically damaged before being killed;
4. the Levitical sacrifices were by and large for unintentional sins, so if Jesus was a Levitical sacrifice it was only for my unintentional sins, which means I cannot be saved;
5. The Passover sacrifice wasn't for sins anyway;
6. God abhors human sacrifice.

Jesus of course did die for our sins - PTL. But He was not a fulfillment of the Levitical sacrifices. So it wouldn't have been a problem for the early Christians to continue in Temple worship - just as it wasn't a problem for Paul in Acts 21 to engage in sacrifice.

There are ways in which Jesus' death was like a sacrifice, in that he gave up his life and was a substitute, but this doesn't mean he was actually a sacrifice. The Bible says, "All men are grass." No one thinks this means we are actually grass.

Rather His death was the death of the righteous which affect atonement for sins. Since He was perfectly righteous, His death is the perfect atonement. How do we find forgiveness? The answer is simple: through repentance, and Jesus' death is the mechanism through which God forgives us.

Obviously this is hard to accept as we have been taught for the last 1800+ years that Jesus fulfilled the sacrifices. But you know, there's a difference between the traditions of men and the word of God... but I'm not sure I'll get many votes for this answer!

Although Christ's atonement fulfilled the "sacrificial ordinances" of the law, and this preparatory ordinance discontinued, as evident in Luke the temple endowment ordinances providing the "promise of the Father," of eternal life, were continued by the resurrected Lord. The Savior said, "I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued [endowed] from on high"(Luke 24:49). The endowment from on high being a temple ordinance they therefore "were continually in the temple, praising and blessing God" (24:53), as is also evident in Acts chapter 2.

In summary we may say that other temple ordinances besides sacrifices were provided in the temple, especially "the endowment from on high" the "promise of the Father" for obtaining eternal life, were continued by the Resurrected Lord.

The answer is: the parents of Jesus, Jesus, all apostles, and the first disciples were all Jews!! Jesus Himself continued to worship in the Temple. They all did! They did not bring Christians into “ the church” until Jesus told them to take the gospel to the nations. They never stopped being Jews- and they were the first Christians. The entire Bible is authored by Jews- and most of it is written to the Jews. Mostly where Paul planted his churches, in his epistles, are the gentiles addressed. Otherwise each book is written to the Jewish Christians. Only Luke’s Jewishness is in question. If you study early church history you find that the early church fathers ( beginning of Roman Catholicism—Augustine, Hillary, etc.) began to hate the Jews and they ended up, after about 300-400 years, being run out of the church. Constantine the Jew hater sealed that deal. Our true early church fathers were the Jewish apostles and disciples. Satans plan of hatred continues in many churches today, thanks to Martin Luther (wrote The Jews and Their Lies) and Calvin from the reformation. Because they could not convert the Jews, they hated them. We have all been fed a lie about “the church” since the day of the crucifixion. Satan has been at the helm of destruction of the Jews since they are God’s chosen people. We gentiles were blessed to be grafted in to the Jewish tree where we receive our spiritual gifts. Jesus is a Jew and will return a Jew. If you study the Bible with a Hebrew mindset vs the typical Greek mindset you will understand and you eyes will be open. Thank God that He brought us gentiles into His Jewish family so all humanity could know Him!

In the beginning, Christians considered themselves Jews. Christianity was Judaism with the additional belief that God sent his Son to earth. And of course, a Jew will attend the Jewish synagog.

Sunday is our holy day because the Christians assembled in church on that day. Why? On Saturday, they were at the synagogs and had to rest afterwards (Jews have specific rules about how many steps one may walk on Sabbath). So they assembled on Sunday before work started.

Later on, pagans (meaning non-Jews) were allowed to become Christians. Slowly, Christians did not see themselves as Jews anymore, but as a separate religion, so they stopped going to synagogs.

You are making an assumption that all ordinances are related to the law of Moses, and that temple work was done away. You might want to read the biblical scholar Margaret barker to see how important the temple was in Christian theology. The Bible never states that the temple work is done away, only that the law of Moses is fulfilled in Christ. If you read texts from that time period you will get a better understanding of how the Jewish people understood the temple. The Christians of the first two centuries identified with the temple. Then again many ideas that are orthodox now were not orthodox then. For instance a doctrine known as 'subordinationalism,' taught that Christ was subordinate to the father, and was the great angel of his presence. At the council of nicea the idea was adopted that the trinity was one in substance and that the three were 'co-equal.' But this ran contrary to Jesus's own statements on the matter who declared that "my father is greater than I." The problem is that this undermined the orthodoxy of the first two centuries. What is orthodox has to do with cultural norms, and it is the same with how the temple is viewed as well as the law of Moses. The bible clearly teaches that the law of Moses is done away but if you look at the beliefs of the early Christians they believed in the importance of the temple, along with continuing revelation. It wasn't until the third century that these things started to truly be undermined. My question would be why do so many Christians assume that the law of Moses and the temple are synonymous?

The simple answer is that in the very early days the followers of Jesus considered themselves to be Jews. They saw Jesus as the fulfilment of the Jewish laws and prophecies - that he had come to redeem Judaism and the Jews, not to set up another religion. The idea that Gentiles might be followers of Jesus without also becoming Jews would only be controversially considered many years later.

Therefore it is entirely natural that they would continue to meet in the Temple. They were also following Jesus' example, who had taught crowds in the Temple only a few months before. The Temple was much more than just the place of sacrifice - it was the central point of the Jewish religion, and the place to go to spread the word to other Jews.
