Ezra 4:1

Ezra 4:1 says, Now when the adversaries of Judah and Benjamin heard that the children of the captivity builded the Temple unto the Lord God of Israel;  As the people of Israel were starting to build the Temple, they met opposition not from their known enemies but from those who considered themselves a part of Israel, the Samaritans. They considered themselves to be the true Israelites according to Matthew Henry and looked on the true Israelites with suspicion.  I do know that there was a lot of animosity on the part of each group towards the other.   Still, as followers of Christ, we should not look on ourselves as being better than anyone else for any earthly reason.  No one is saved because they deserve to be.  There are still groups today who profess themselves to be the true Christians, even as they change God's word, and they look on true Christians as being unsaved. Verse two adds, Then they came to Zerubbabel, and to the chief of the fathers, and said unto them, Let us build with you: for we seek your God, as ye do; and we do sacrifice unto him since the days of Esarhaddon king of Assur, which brought us up hither. They came to Zerubbabel claiming worship the same God and offering to help build the Temple.  Matthew Henry says that even though they had professed to worship the same God that they worshipped other gods as well.  We cannot allow those who follow false teachings to insert themselves into the church today claiming to worship the same God. There is but one God, and anyone who believes anything else is not a part of the family of God and we need to make sure that they never gain power in the church. On the other hand, if they have accepted Jesus Christ as their Savior and Lord, which is the only way to salvation, and offer to help, even if they are somehow different than us in some earthly way, we should not refuse their help.  All Christians are spiritually the same and none is better than any other because of worldly standards.  Verse three continues, But Zerubbabel, and Jeshua, and the rest of the chief of the fathers of Israel, said unto them, Ye have nothing to do with us to build an house unto our God; but we ourselves together will build unto the Lord God of Israel, as king Cyrus the king of Persia hath commanded us.  Zerubbabel and Joshua and the other elders told them that they had nothing to do with the building of the Temple, and anyone who isn't a Christian still doesn't have any part in building the church today. God's church cannot be built by those who hold beliefs that are not in accordance with God's word. Still, the good news is that if they accept Jesus Christ as their personal Savior and Lord, then they are a part of His family and can begin helping in the building of the church.
