The doctrine of the Trinity is encapsulated in Matthew 28:19, where Jesus instructs the apostles: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." So are you saying that the Trinity is un-Catholic? Really.....really???
“encapsulated”
This is my point - there are doctrines “encapsulated’ that are not explicity named. Many Catholic martyrs died defending the heresy of Arianism, which questioned the Trinitarian concept of Christ’s Divinity - of course we are the foundation of the doctrine of the Trinity.
This is also my point. Non catholics need to stop bashing catholcis because they have no clue as to what we actually believe vs. what they have been told FALSELY that we believe.
