The basic idea is not about property calling it theft or not self made. The basic idea is " from each according to his ability and to each according to his need". This is the same basic idea behind slavery which is why it is no coincidence that every communist nation is a slave state.
They got it from the Bible.
That is not a defense of slavery, nor does it lend legitamacy to an evil idea.

Nobody takes right-wingers seriously about any "gospel Truth". Appeals to ignorance is all right-wingers are best at.
All who believed were together and had all things in common; 45 they would sell their possessions and goods and distribute the proceeds to all, as any had need. ... Now the whole group of those who believed were of one heart and soul, and no one claimed private ownership of any possessions, but everything they owned was held in common. ... There was not a needy person among them, for as many as owned lands or houses sold them and brought the proceeds of what was sold. They laid it at the apostles' feet, and it was distributed to each as any had need.[25]
— Acts 2:44–45, Acts 4:32–35
