what does it mean to say you cannot serve god and mammon
Matthew 6:24 This famous verse continues the discussion of wealth, and makes explicit what was implied in Matthew 6:21: a person cannot pursue both material goods and spiritual well being. The two goals are mutually exclusive.
Liturgy The term "liturgy" literally in Greek means "work for the people", but a better translation is "public service" or "public work", as made clear from the origin of the term as described above. The early Christians adopted the word to describe their principal act of worship, the Sunday service (Holy Eucharist, Holy Communion, Mass or Divine Liturgy). This service, liturgy, or ministry (from the Latin "ministerium") is a duty for Christians as a priestly people by their baptism into Christ and participation in His high priestly ministry. It is also God's ministry or service to the worshippers. It is a reciprocal service. As such, many Christian churches designate one person who participates in the worship service as the liturgist. The liturgist may read announcements, scriptures, and calls to worship, while the minister preaches the sermon, offers prayers, and blesses sacraments. The liturgist may be either an ordained minister or a layman. The entire congregation participates in and offers the liturgy to God.
