The concept of the Holy Trinity is a part of many Christian churches across the world. The word ‘holy’ refers to something divine, while the word ‘trinity’ is a name used to refer to something, which exists in three different forms (Goggin, 2000). To the Catholics, the divine nature of God is represented in three different forms. These forms include God the Father, God the Son (Jesus Christ), and God the Holy Spirit. This is evident in the Catholics’ Nicene Creed (known as the Apostle Creed by the protestant churches), which is recited by the believers during mass (Goggin, 2000).
In the concept of the Holy Trinity, the Catholics proclaim to believe in God as the Father of the Universe (Sleman, n.d.). For this reason, they always refer to God as ‘our Father’ during prayers, praise, as well as in summons. The belief that God is the Father of the Universe is based on different instances found in the Bible, which imply that God is, indeed, the Father of the Universe. In his teachings, St Paul calls God the ‘Father of our Lord Jesus Christ’ (II Corinthians 1:3, Ephesians 1:3, Ephesians 3:14). In the Bible, Jesus also refers to God as His Father. For example, in John 16:28, Jesus says, “I came forth from the Father…” Besides, there are also many instances in the Bible where God is referred as the Father of all. For example, in the Old Testament, Moses says to the Israelites, “Is not God your Father? Has He not created you?” (Deuteronomy 32:6). St Paul also says “there is one God, the Father, of whom are all things, and we for Him” (1 Corinthians 8:6). All these and other instances in the Bible imply that God is the Father of all creation. Therefore, the Catholics believe in God as the Father of the entire Universe.
The concept of the Holy Trinity also entails to believe in God the Son. That is, God and the Son (represented by Jesus Christ) are the same person (Sleman, n.d.). There are many instances in the Bible, which refer or rather imply that God and Jesus are the same person. For example, in the Book of Zechariah, Jesus is referred as the ‘branch’ of the Father, through whom the Father reveals Himself to us (Zechariah 3:8, 6:12). In addition, Jesus Himself said, “The Father is in me, and I in the Father” (John 10:38). Again, in John 10:30, Jesus says, “I and the Father are one.” All these form the foundation of the belief that Jesus Christ is the true manifestation of the invisible God (Sleman, n.d.). Therefore, the Catholics believe that when they speak of Jesus, they speak of God, and when they pray to Jesus, they pray to God as well.
God, who is also the Father and the Son, exists on the earth in the form of the Holy Spirit (Sleman, n.d.). In John 4:22 and Second to the Corinthians 3:17, God is referred as ‘Spirit’. In addition, when Jesus (who is the true manifestation of the invisible God, thus God Himself), was ascending to heaven, He said to His disciples that He would send the Holy Spirit to guide them. This implies that God the Father, who is also the Son, sent His Spirit to act as a guide of the human beings. Therefore, God exists in the form of a spirit, which is the Holy Spirit. For this reason, the Catholics believe that God lives on the earth by His Spirit. They, therefore, consider that believing in the Spirit of God is the same as believing in the Holy Spirit, which is the same as God who is the Father of the Universe (all creation) as well as the Son (Jesus Christ).
The Catholics base the concept of the Holy Trinity as the three forms in which God exists. They believe that God is the Father of all creations, including Jesus Christ. They also believe that God is the same as Jesus Christ. They believe that Jesus is the true manifestation of the invisible God. Furthermore, they believe that God, who is the Father and the Son, is also the Holy Spirit because He sent His Spirit to the earth to act as a guide of all mankind. Therefore, God exists in three holy (divine) forms: God the Father, God the Son, and God the Holy Spirit.
