Do you beleive in Holy Trinity?

no I don't

Every Catholic has to believe in the Holy Trinity. The Holy Trinity is the main reason why today, every catholic, young or old, will proclaim the Niceas Creed against their heart. The Holy Trinity was first discussed upon during the First Coucil of Nicea, that's actually a long time before the first modern bible came to be compiled as it is today. The Holy Trinity speaks of three persons of God, The Father, The Son and The Holy Spirit. I can't remember much details of hand, but I'll try to dig up my study log and continue from there.

yes I do because Jesus did !he told in Matthew 28: 18. Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20. and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
