691 “Holy Spirit” is the proper name of the one whom we adore and glorify with the Father and the Son. The Church has received this name from the Lord and professes it in the Baptism of her new children.
The term “Spirit” translates the Hebrew word ruah, which, in its primary sense, means breath, air, wind. Jesus indeed uses the sensory image of the wind to suggest to Nicodemus the transcendent newness of him who is personally God’s breath, the divine Spirit. On the other hand, “Spirit” and “Holy” are divine attributes common to the three divine persons. By joining the two terms, Scripture, liturgy, and theological language designate the inexpressible person of the Holy Spirit, without any possible equivocation with other uses of the terms “spirit” and “holy.”
I found the Holy Spirit to be the most “foreign” out of all the Holy Trinity. Now, why foreign you may ask? I am not 100% sure. Is it because I do not know what the Holy Spirit looks like? Or maybe because I am yet to master the art of speaking in tongues? Out of the 3, I believe the Holy Spirit signifies most believers’ challenges with faith on a whole. The lack of tangibility associated with believing in God has been a stumbling block in understanding my faith. I have however, come to a conclusion that the Holy Spirit is like love, light, air. You don’t need to touch or see it to believe that it exists. All you need to do is open yourself towards feeling the presence of the Holy Spirit and you would realise it’s been inside you, apparently dormant to you but in reality always active in our lives daily.
The Holy Spirit is the personification of the divine love shared between the father and the son. Through baptism, we get a God light “bulb” installed in us. It is our responsibility as Christians to keep that light shining bright at all times for the world to see. So we can use a metaphor – lets say each sacrament is like a filling station with the Holy Trinity being the fuel source needed to keep the light bulb on. We have to consistently visit each filling station on this journey called life…Which means we have to consciously foster a relationship with God the Father, God the Son and God the Holy Spirit through each sacrament because in doing so, “Nepa” can never take your light!
