Ordination to the Sacred Priesthood is a consecration, totally giving self to God. We pray for our 20 beloved sons, as they take this major step in their lives this year. May the grace of God continue to flower and increase in their lives, living their lives in the name and in the person of Christ.

HOLY SEASON OF LENT
We have entered the Holy Season of Lent, 40 days of prayer, fasting and almsgiving. For effective prayer this season, don’t be selfish in your prayers; pray for others also, and not only for yourself, thanking God for His graces, goodness, and blessings. For good fasting, the first and best fasting is to fast from sin, run away from any sin, both mortal and venial sins. And for our almsgiving to be fruitful, there are a lot of people around us that need our help, start from them, our neighbourhood, those living around us, and avoid unnecessary publicity of our almsgiving. The Archbishop prays for all of us, and for our intentions throughout this Holy Season of Lent, that God may be with us with His Grace, so that we may journey with Him in faithfulness.

2025 Pastoral Letter
A healthy society is a function of healthy families while at the same time, a healthy family is rooted in a healthy marriage. A healthy marriage gives rise to a healthy family, while healthy families give birth to a good society, a healthy Church and spiritually prosperous souls raised for the household of God and sustenance of the society. (art 5)
AND THE TWO BECOME ONE: TOWARDS A CHRISTIAN MARRIAGE
