I believe in one God, the Father Almighty, Creator of Heaven and Earth. He was conceived by the Power of the Holy Spirit and was conceived by the Virgin Mary. He suffered under Pontius Pilate, was crucified, died and was buried. He descended to the dead. "On the Third day He rose again". He ascended into Heaven and is Seated at the Right Hand of The Father. He will come again to judge the living and the dead. His Kingdom will have no end.
I believe in the Holy Spirit, the Catholic Apostolic Church, the Communion of Saints, the Resurrection of the Body (Jesus) and life everlasting Amen.

Short version of The Apostles Creed left by Jesus relating again to the Third Day He rose again. On the Third day. Friday Jesus died. Saturday Jesus was placed into the Tomb and thereafter spoke to Mary Magdalene. Now, whether Jesus ascended into Heaven on either Sunday or Monday would be unclear to any one other than Jesus/God/The Holy Spirit (The Holy Trinity) because Jesus said to Mary M " that he had not yet ascended into Heaven". He was in the Holy Spirit but had not yet ascended into Heaven. Therefore when we say 'on the Third Day" as Catholics, we are going by the Apostles Creed which was left to us by Jesus in His Scriptures. It comes from His Bible of Scriptures.

'Mark 8:31

Then He began to teach them that the Son of Man must undergo great suffering, and be rejected by the Elders the Chief Priests, Pharisees and the Scribes and be killed and after three days rise again. He said all this quite openly. And Peter took Him aside and began to rebuke Him. "Get behind me Satan! For you are setting your mind not on divine things but on human things".

He called the crowd with His Disciples and said to them"if any want to become my followers, let them deny themselves and take up their cross and follow Me. For those who want to save their Life will lose it and those who lose their life for My sake and for the sake of the Gospel, will save it. For what will it profit them to gain the whole world and forfeit their Life? Indeed what can they give in return for their Life?Those who are ashamed of Me and My Words, in this adulterous and sinful generation of them the Son of Man (Jesus) will also be ashamed when he comes in the Glory of His Father with the Holy Angels".

"Truly I tell you there are some standing here who will not taste death until they see that the Kingdom of God has come with power".
