The spreading of Christian teaching need not provoke antagonism, or harm those who do not know our doctrine. Caritas omnia suffert! — love bears all things. If one proceeds with charity, anyone who might otherwise have been opposed to Christianity and been deceived by error may easily and honestly end up committing himself to it. —However, there can be no giving ground in dogma in the name of a naive “breadth of belief”, for if anyone acted in this way he would risk putting himself out of the Church. Instead of winning a benefit for others he would harm himself.
If you really love your own country, and I am sure you do, you would not hesitate to enlist as a volunteer to defend it from imminent danger. As I wrote to you before, everyone can be useful in an emergency: men and women; the old, the middle-aged, the young and even adolescents. Only invalids and children are left out.
Every day there is a call, not just for volunteers to enlist — that is very little — but for a general mobilization of souls to defend Christ’s Kingdom. And the King himself, Jesus, has called you expressly by your name. He asks you to fight in God’s battles, and to put at his service the noblest powers of your soul: your heart, your will, your understanding, all your being.
—Listen to me: the flesh, with your clean life and especially with the protection of the Virgin Mary, is no problem. Are you going to be such a coward as to try to get out of being enlisted with the excuse that your heart or will or intellect are weak? Are you going to pretend to claim some grounds for remaining in the ancillary services?
—The Lord wants to make you an instrument for the front line —you are one already— and if you turn your back you deserve only pity, as a traitor.
Josemaria Escriva, Furrow 962
