St. Patrick, The Shamrock, and The Holy Trinity

   It's not secret that the shamrock is the symbol of St. Patrick's Day. But do you know why?

   St. Patrick used the shamrock as a symbol to explain the Trinity to Unbelievers. He used the three leaves/leaf with three parts as a physical symbol to show God is One God in Three Persons. 
Go ye therefore, and teach all nations, baptizing them in the Name of the Father, and of the Son, and of the Holy Ghost(Matthew 28:19). 

   Patrick would hold up a shamrock and challenge his hearers, “Is it one leaf or three?” 

   “It is both one leaf and three,” was their reply. 

   “And so it is with God,” he would conclude. 

yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live (1 Corinthians 8:6) 

Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom (2 Corinthians 3:17)

   Of course, doctrines such as the Trinity or the Divinity of Jesus Christ can only be received by willing hearts, who have committed themselves to obey whatever the Spirit reveals from the Scriptures, and for any heart to be willing it must have understanding. St. Patrick undoubtedly knew this, and with his own guidance from the Holy Spirit was able to bring understanding through the symbolism of the shamrock. 
 If any man will do His will, he shall know of the doctrine (John 7:17). 

There is one body and one Spirit, just as you were called to one hope when you were called; 
one Lord, one faith, one baptism; 
one God and Father of all, who is over all and through all and in all. (Ephesians 4:4-6)
