If by "Marxist" you imply an advocacy that the government confiscate and control all property, I would again challenge you to provide us with specific verses. I do find many verses throughout the New Testament exhorting and commending VOLUNTARY charitable giving, but that is most certainly NOT the same thing as Marxism. Indeed, if you actually read Marx you would find that he had nothing but contempt for such.
The Acts of the ApostlesIf by "Marxist" you imply an advocacy that the government confiscate and control all property, I would again challenge you to provide us with specific verses.004:031 And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness. 004:032 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. 004:033 And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all. 004:034 Neither was there any among them that lacked: for as many as were possessors of lands or houses sold them, and brought the prices of the things that were sold, 004:035 And laid them down at the apostles' feet: and distribution was made unto every man according as he had need. 004:036 And Joses, who by the apostles was surnamed Barnabas, (which is, being interpreted, The son of consolation,) a Levite, and of the country of Cyprus, 004:037 Having land, sold it, and brought the money, and laid it at the apostles' feet. 005:001 But a certain man named Ananias, with Sapphira his wife, sold a possession, 005:002 And kept back part of the price, his wife also being privy to it, and brought a certain part, and laid it at the apostles' feet. 005:003 But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land? 005:004 Whiles it remained, was it not thine own? and after it was sold, was it not in thine own power? why hast thou conceived this thing in thine heart? thou hast not lied unto men, but unto God. 005:005 And Ananias hearing these words fell down, and gave up the ghost: and great fear came on all them that heard these things. 005:006 And the young men arose, wound him up, and carried him out, and buried him. 005:007 And it was about the space of three hours after, when his wife, not knowing what was done, came in. 005:008 And Peter answered unto her, Tell me whether ye sold the land for so much? And she said, Yea, for so much. 005:009 Then Peter said unto her, How is it that ye have agreed together to tempt the Spirit of the Lord? behold, the feet of them which have buried thy husband are at the door, and shall carry thee out. 005:010 Then fell she down straightway at his feet, and yielded up the ghost: and the young men came in, and found her dead, and, carrying her forth, buried her by her husband. 005:011 And great fear came upon all the church, and upon as many as heard these things. 005:012 And by the hands of the apostles were many signs and wonders wrought among the people...
Technically speaking, Peter is not acting as a government official in these passages, but there is a strong implication that Peter used either his own strength of will, or maybe The Holy Ghost Itself, to shame and humiliate Ananias and his wife unto their deaths, simply because their oblation failed to satisfy him.
Keep in mind that this is the same Peter who betrayed Jesus thrice as often as did Judas; furthermore, Judas was warned in only very general terms that he would betray his master, while Peter was warned in the most explicit of terms.
I know of no passage in the Christian books of the New Testament in which Jesus causes the mortal death of a living man [although he certainly goes to great lengths to warn of the possibility of immortal death, which is to say, the withholding of immortal life]. The mistake that is made by almost all people who call themselves Jews and Christians is in assuming that the men whose lives are depicted in the Bible are good and decent men. King David was a wicked, evil, iniquitous man. Simon-Peter was a wicked, evil, iniquitous man. Saul-Paul of Tarsus was a wicked, evil, iniquitous man.
The Old Testament is a history of the evil, wickedness, and iniquity of the Hebrew people. The post-Christian chapters of the New Testament are a history of the evil, wickedness, and iniquity of men who called themselves Christians.
