However, earliest Christianity has always defined prayer as
conversation, as in conversation with God. Conversation, as
any other act of communication ( e.g., talking, conversation,
yelling, etc.), requires a sign of the direction of the
communication: one talks to someone, communicates with
someone, prays to someone, converses with someone, yells at
someone, etc. Hence, praying to God, a Saint, the Virgin Mary
indicates simply the direction of prayer communication. It is more
a matter of grammar and understanding communication than
acknowledging the worship of the receiver.
From the earliest of Church Councils (the Council of Rome, 993,
defined by the Council of Trent) the distinction was made
between worship and honor.
Catholics believe that worship is due to God alone. Catholics
honor those saints who have gone before us as a sign of faith
and victory in living the Christian life.
