I have known various Bible trusting people who clearly understand that our jobs are first for reaching people for Christ. They put us in our mission fields. So, I am curious who you mean by "the church", here. Ok, so it is possible that a number of Catholics have separated priesthood from secular living. And so it can be deemed innovative for a priest to get a job in order to bring influence into the community and world.
But there are people who always have understood how Jesus would have them work for a living, but use their job place as a mission field.
And we all are in Jesus Christ's priesthood, according to what I read in our Apostle Peter's epistle > Peter says we are
"a royal priesthood" (in 1 Peter 2:9).
And included in the priesthood of Jesus is > Hebrews 4:15 >
"For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin." (Hebrews 4:15)
To me, this is clear how Jesus Himself went through things of life which we go through "in all points" so that now Jesus as our High Priest can feel for us and bless us with the grace which made Him do so well while going through everything we do . . . but without sin.
And so > I can see through this > how we join in this priesthood of Jesus, by using our experiences to help us feel for others and bless them with the grace which blesses us to do well while going through anything. Among other things, we with Jesus find how to love in our marriages and how to bring up our children, so now we can help others with their marriages, plus help single people to prepare for this.
And our Apostle Paul therefore gave very clear directions about who qualifies to "take care of the church of God" > 1 Timothy 3:1-10 > a family man who has proven himself at home and has become "blameless" in God's love maturing him with his wife > so now they can function in Christ's priesthood of using their experience and maturity of grace to help other married people and help single people to know how to relate in love and live in submission to how our Father cares for us and guides us in His own peace > Colossians 3:15. So, Paul wants people to go through things, themselves, so now they can have compassion for and help others; and by doing this, they can function in this priesthood of how Jesus went through things so now He can minister to us.
So, I am sure the Bible means how Christ's priesthood operates in marriage and the workplace.
Also, Paul says,
"And walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet-smelling aroma." (Ephesians 5:2)
To me, this shows how Jesus on Calvary was sweetly pleasing our Father while Jesus gave himself for us. He was sweet-smelling while He was making His sacrifice.
And Paul is clear > this is how we all are to walk. This means if we make our sacrifice of working, among other things, we are to be sweet-smelling to God while making our sacrifice. We do not waste ourselves and burn ourselves out in workaholic egotistical controlling, but we are gentle and humble "and you will find rest for your souls." (in Matthew 11:28-30)
So, we aren't burnt-out sacrifices but sweetly pleasing our Father.
And so we can test if we are doing what God has called us and is personally guiding us to do. Prayerfully test to see what God has us doing while we are obeying Him in His peace ruling us > Colossians 3:15 < this is basic to what we are "called in one body" to do; this is for every child of God. We do exactly what our Heavenly Father personally rules us to do in His peace. We prayerfully test, even at each moment, to see how God's peace has us be and has us see things, and to discover how our Creator's peace makes us creative to do what is loving each and every person.
And so, by being sweet-smelling in all our sacrifices, we are in the love which had Jesus on the cross sacrifice Himself for us. And so every one of us who obeys Ephesians 5:2 is functioning in the priesthood of Christ on the cross.
So, may be this is what you would mean by the universal cruciform priesthood, of all believers.
Jesus on the cross so suffered and died with hope for any and all people. And Paul says love "hopes all things", in 1 Corinthians 13:7. So, we are sharing with Christ on the cross, by having hope for any impossible person, at all, in our workplace and at home.
"nor as being lords over those entrusted to you, but being examples to the flock." (1 Peter 5:3)
Jesus has been our Example, on the cross; and now we join His priesthood of example, by also feeding people our example.
