The Holy Trinity is an extremely important yet mystical doctrine of the Christian faith. It defines ‘the only one God’ in three aspects, that is, the Father, the Son, and the Holy Spirit.
The Father refers to God the Father (Almighty), the Son refers to Jesus Christ, and the Holy Spirit is the Spirit of the Lord that exists all through eternity.
According to the Trinitarian theology, God the Father is considered the eternal source of Godhead. Hence, He is considered the “origin” or “source” of the Son of god and the Holy Spirit, too.
Of these three, the Holy Spirit, also referred to as the “quiet third” is the least understood because it has no personal name and body. Nevertheless, the Holy Spirit is often symbolized as a dove surrounded by angels.
“But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.”
~ John 14:26
Thus, the Holy Trinity defines God in three divine persons. These three persons, however, are distinct. Hence, although Christianity believes that there is only one God, it also refers to the Father as God, the Son as God, and the Holy Spirit as God.
Jesus explains in Mark 12: 29-30 that the greatest and the most important commandment is that the Lord is one and we should love Him sincerely.
“The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’”
Plus, the Scripture states that Jesus Christ is not the Father, nor the Holy Spirit. Similarly, it shows that the Father is not the Holy Spirit. During the Baptism of Jesus, in particular, all the three persons from the doctrine of Trinity were manifested together.
“When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: ‘You are my Son, whom I love; with you I am well pleased.’”
~ Luke 3:21-22
“For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one.”
~ 1 John 5:7

Simply put, the whole creation and works of grace come from the Father, through the Son, and in the Holy Spirit. Therefore, the Christian faith teaches us to worship one God, the single divine nature, in the Holy Trinity.
However, due to our limited human intelligence, though, it is not possible for us to understand God and the Holy Trinity in perfect detail.
Moreover, the term Holy Trinity” does not appear in the Bible yet makes it apparent that the Father, the Son, and the Holy Spirit share the same substance and constitute divine unity.
