The Deacon has the basic powers of Holy Orders, and is allowed
preach and confer blessings. Deacons aid the Priests and Bishops in
any way that is needed. Deacons also serve the people, especially
the poor and the needy. The Deacons also distributes Communion.
They are like a bridge between the clergy and the laity.
The Priest has more powers. He is allowed to say Mass, hear
confessions and absolve sins in the name of Christ. The Priest is
always on standby for sick call, bringing Christ's peace to the
those in their last moments.
The Bishop exercises the fullness of Holy Orders. The Bishop is the
head of a group of parishes in a certain geographical area. He has
the authority to ordain Deacons and Priests. All clergy and laity
are subordinate to their Bishop. St Ignatius says, "Where the
Bishops are, there is the Catholic Church."
In any case, one thing is certain: All clergy must be ready to die
for their flocks, if need be. We must pray for our clergy
always.
