Today the Church celebrates the Feast of the Holy Trinity. Since A.D. 200, Christians have described God as the Holy Trinity or three persons in one. It is the central belief or doctrine of the Church and has been celebrated as the feast of the Holy Trinity since the ninth century.
Despite this longstanding doctrine or belief, the Trinity, according to the Catechism of the Catholic Church “is a mystery of faith in the strict sense, one of the ‘mysteries that are hidden in God, which can never be known unless they are revealed by God’” (237). So how can we better understand this mystery and live it out in our marriages and families?
The Holy Trinity is a divine community of life and love, the intimate community of three persons, the Father, the Son, and the Holy Spirit. God created us “in his own image, in the image of God he created him; male and female he created them” (Gen 1:27). We were created in the image of God who lives and loves in intimate community.
