Who are we speaking about? In Acts were told from the very begining the donations made by the early Christians were to help all the Jews who came to Jerusalem from the distant providences of the Roman Empire. The donations in Acts 2 were used to help these new converts remain in Jerusalem so they could get more instruction, nothing was used for the Apostles Retirement Package because they all were going to die(except John).
Acts 2:
42All the believers devoted themselves to the apostles’ teaching, and to fellowship, and to sharing in meals (including the Lord’s Supper i ), and to prayer.
43A deep sense of awe came over them all, and the apostles performed many miraculous signs and wonders.44And all the believers met together in one place and shared everything they had. 45They sold their property and possessions and shared the money with those in need. 46They worshiped together at the Temple each day, met in homes for the Lord’s Supper, and shared their meals with great joy and generosity j— 47all the while praising God and enjoying the goodwill of all the people. And each day the Lord added to their fellowship those who were being saved.
Acts 20:
25 “And now I know that none of you among whom I went about teaching the Kingdom will ever see me again. 26 Let me say plainly that no man’s blood can be laid at my door, 27 for I didn’t shrink from declaring all God’s message to you.
28 “And now beware! Be sure that you feed and shepherd God’s flock—his church, purchased with his blood—for the Holy Spirit is holding you responsible as overseers.29 I know full well that after I leave you, false teachers, like vicious wolves, will appear among you, not sparing the flock. 30 Some of you yourselves will distort the truth in order to draw a following. 31 Watch out! Remember the three years I was with you—my constant watchcare over you night and day and my many tears for you.
32 “And now I entrust you to God and his care and to his wonderful words that are able to build your faith and give you all the inheritance of those who are set apart for himself.
33 “I have never been hungry for money or fine clothing— 34 you know that these hands of mine worked to pay my own way and even to supply the needs of those who were with me. 35 And I was a constant example to you in helping the poor; for I remembered the words of the Lord Jesus, ‘It is more blessed to give than to receive.’”
1 Thess 2:
1You yourselves know, dear brothers and sisters, a that our visit to you was not a failure. 2You know how badly we had been treated at Philippi just before we came to you and how much we suffered there. Yet our God gave us the courage to declare his Good News to you boldly, in spite of great opposition. 3So you can see we were not preaching with any deceit or impure motives or trickery.
4For we speak as messengers approved by God to be entrusted with the Good News. Our purpose is to please God, not people. He alone examines the motives of our hearts. 5Never once did we try to win you with flattery, as you well know. And God is our witness that we were not pretending to be your friends just to get your money! 6As for human praise, we have never sought it from you or anyone else.
2 Corth 8:
14 Now I am coming to you again, the third time; and it is still not going to cost you anything, for I don’t want your money. I want you! And anyway, you are my children, and little children don’t pay for their father’s and mother’s food—it’s the other way around; parents supply food for their children. 15 I am glad to give you myself and all I have for your spiritual good, even though it seems that the more I love you, the less you love me.
16 Some of you are saying, “It’s true that his visits didn’t seem to cost us anything, but he is a sneaky fellow, that Paul, and he fooled us. As sure as anything he must have made money from us some way.”
17 But how? Did any of the men I sent to you take advantage of you? 18 When I urged Titus to visit you and sent our other brother with him, did they make any profit? No, of course not. For we have the same Holy Spirit and walk in each other’s steps, doing things the same way.
Taking out the parts of the Bible where the Christians decided to share their monies with believers who were suffering from hard times, there is no evidence the Rank and File Christians were the Apostles Pension Plan!
The Watchtower would surely love to have this in print but they don't and can't use the Bible to demand the Jewish custom of a Tithe, there's no proof, nothing, nada, zilch!
