One way to answer this question is to look inside a monastery or convent, where a ‘Rule’ that is particular to whichever order of religious is gathered there is designed to encourage Christian living in its most perfect form. Here, besides prayer, you will find an emphasis on work, sharing, and undifferentiated property, all of which (except for prayer) does resemble communism of the Marxist variety, though that resemblance ends once you begin to examine the motivations. For Christian communism is much older, and has no socio-economic or political ideology as it basis, but instead originates in the charity that is natural to a man or woman who has begun to imitate Christ, and to place the good of their soul, as well as the souls of their brethren, above other considerations.
