proper for a Christian to observe or commemorate. Not all beliefs and customs are bad. However, God does not approve of customs if they come from false religion or are against Bible teachings. (Matthew 15:6) If a holiday or custom is being deliberately used in worship by a Christian, it must have absolutely no known pagan religion associations or unscriptural teachings. (2 Cor. 6:16, 17; 1 Thess. 1:9)There are many things or occasions where it is
Notice what the following source tells us about St. Patrick's Day:
"The doctrine of Three Gods in One, each separate and distinct, yet each totally God, is claimed by Christians to be a mystery and is accepted on faith. In trying to teach his converts about the Trinity, St. Patrick held up a shamrock explaining that the three leaves represented the Father, the Son, and the Holy Spirit, while the stem was the Godhead itself from which they proceeded. This is said to be the origin of the use of the shamrock which is customarily worn on St. Patrick's Day.
"Scholars have discovered that the shamrock, or trefoil, was initially used in ancient Celtic fertility rites. It represented a triad of goddesses..." - pp. 79-80, Celebrations - The Complete Book of American Holidays, Robert J. Myers, Doubleday; Co., 1972.
Not only does Biblical and historical evidence clearly not support the Trinity, but Historian Will Durant said that
paganism; it adopted it. . . . From Egypt came the ideas of a divine trinity."
And Arthur Weigall stated that
"Nowhere in the New Testament does the word `trinity' appear. The idea was only adopted by the Church three hundred years after the death of our Lord; and the origin of the conception is entirely pagan." - The Paganism in our Christianity, pp. 197, 198.

Should we venerate "saints" as intercessors with God?
Notice what Peter's response was to a certain situation in the account of Acts 10:25, 26, JB:
"As Peter reached the house Cornelius went out to meet him, knelt at his feet and prostrated himself. But Peter helped him up. `Stand up,' he said `I am only a man after all!'"
Peter did not approve of such adoration when he was personally present. He understood what Jesus clearly stated in John 14:6, 14 that our approach to the Father can be only through Jesus and that our requests are to be made in Jesus' name:
"Jesus said: `I am the Way, the Truth and the Life. No one can come to the Father except through me. If you ask for anything in my name, I will do it.'" (JB)
1 Tim. 2:5: "For there is one God, and one mediator also between God and men, the man Christ Jesus." (NASB)
Note what Martin Luther wrote concerning the reverence of Roman Catholic Saints:
"The pity is that we are so blind that we do not leave the devil alone to play his tricks in his own way; rather, we support him and multiply them. I wish people would leave the saints in peace, and not mislead humble folk. What spirit was it that gave the pope authority to canonize saints? Who tells him whether they are holy or not? .... God is just in judging us with His wrath and in allowing the devil to lead us hither and thither, to institute pilgrimages, ... to set about canonizing saints and other foolish things." - p. 458, Martin Luther, Selections From His Writings, Dr. John Dillenberger, Anchor Books, Doubleday & Company, Inc., 1961.
