The Pharisees and Sadducees approached the Lord once and asked Him to show them a sign from heaven to which the Lord responded, “When it is evening you say it will be fair weather for the sky is red. And in the morning, it will be foul weather for the sky is red and lowering. O ye hypocrites, you know to discern the face of the sky but you don’t know to discern the sign of the times” (Matthew 16:3-4).
Today is the feastday of St. Elijah the Prophet, according to the old calendar of the Church, and it is this feastday (and actually this month of August) which is connected with many sayings among the Serbian people, many “signs” from the sky. For instance, since the heat of the summer days tend to cool down beginning in August, not to mention the days get shorter, the saying is After St. Elijah, the sun is more delightful. There is also no more swimming in the rivers after Transfiguration and if it is a nice day on Transfiguration there will be good wine. If there is rain in August more wine. If ants make bigger ant hills, the winter will be colder. If there is wind on the feastday of the Assumption of the Most Holy Theotokos, there will be more snow.
How we know – and care – what the weather will be like but have little concern for the fate of our souls. Hypocrites is right. May God be merciful on us all through the prayers of St. Elijah the prophet and all the Saints. Amen.
