Acts 4:32 "And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common."
As I see it, they didn't give EVERYTHING to the church. They still possessed money and things, while allowing the Lord to ultimately steward it all. "He possessed" denotes that the believer still possessed money and things of value (while not considering them to be "his own").
I do not believe that the following verses contradict this... Acts 2:44 "And all that believed were together, and had all things common; 45 And sold their possessions and goods, and parted them to all men, as every man had need."
The fact that they had all things common does not automatically denote that there was a communal account...which held "Everything". That thought would be debunked as soon as any sum was shared with a member of the "communal living arrangement". I would also like to note that verse 45 does not say "ALL of their possessions and goods".
It's also quite evident that Generosity ruled the day and materialism didn't. Acts 4:34 "There were no needy ones among them, because those who owned lands or houses would sell their property, bring the proceeds from the sales, 35and lay them at the apostles’ feet for distribution to anyone as he had need."
The following passage also bears witness to the fact that "Lying to the Holy Spirit" was Ananias and Sapphira's sin, not "Holding back a part". Acts 5:1 But a certain man named Ananias, with Sapphira his wife, sold a possession. 2 And he kept back part of the proceeds, his wife also being aware of it, and brought a certain part and laid it at the apostles’ feet. 3 But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit and keep back part of the price of the land for yourself? 4 While it remained, was it not your own? And after it was sold, was it not in your own control? Why have you conceived this thing in your heart? You have not lied to men but to God.”
Added Note: Believer's also sold houses and lands in accordance with Jesus' warning about the impending judgment and destruction of Jerusalem in 70 AD.
Just some food for thought...
