King Ahaz of Judah (in 2 Kings 16) went to Damascus in Syria and was impressed by how they worshiped. So impressed, in fact, that he recorded the dimensions of the Syrian altars and sent them back to Urijah the high priest to build one just like it. That is how a strange altar was introduced into the house of the Lord. The parallels to the modern day church are stunning. Perhaps we should exercise the greatest of caution when considering to adopt the worship of those who do not hold the Truth?
